trying to make character sheets is a fun until you run out of space. early thoughts are that it will be 4 pages total:
Character info, Pilot stats, BIOMECH stats, and BIOMECH weapons. either way, the goal is to make these easier to navigate and read. This is of course a rough draft for the alpha.

working a bit on some prose surrounding the idea of entering and taking control of a BIOMECH. Thought it was neat enough writing to share here, and dips the player's toes into understanding there is some mental toll to Piloting.
This is for the GM to read out

back to writing

#BIOMECH
#BIOMECHTTRPG
You each enter your bodies, taking their muscles as your own. Bodies that are not the ones you started in, but are you all the same. You are it, but it is only a part of you. You are countless bodies, bodies that will do as you tell them because they are a part of You. You are the intent, the thought behind the actions taken. These bodies are simply the tool you use. You have a mission, Pilot.

I know the writing updates are not as cool as the art ones were, but while waiting to test I started actually working on the test mission and writing more than some notes only I know. This is planned to release alongside the full alpha release, and expand to a full adventure for the full release!
Chapter 1: A long, dusty road Hours ago, you set foot for the first time on this planet, Nosa. It is a barren place, mostly comprised of crags, canyons, and arid flats under a blue-green sky. Under its surface, a wealth of minerals in dire need of processing for various war efforts. You have all been contracted to assist SynthSky Armory in recovering three scientists from a mercenary group, Steel Crown. It is assumed the scientists are still alive, and that Steel Crown was paid off by a rival corporation, Luchart Aerospace, to abduct these scientists and extract company information. At the head of Steel Crown is a Dredge going by the name of Sawtooth, he is known to be an exceptionally dangerous criminal on the run from multiple corporations. You will be heading through the Redrock Crags to eventually arrive at the Steel Crown mercenary outpost. Resistance is expected in the canyon, and you have clearance to neutralize any threats as you see fit within. It is ill-advised to go over the canyon, as you will likely be bombarded by rival corporations for moving military equipment out in the open. Eventually, the canyon becomes too narrow for BIOMECH navigation, and you will proceed on foot to the outpost. Once at the outpost, the retrieval of the scientists is paramount. You will be paid additional for the removal of the Steel Crown threat as Central sees fit. Once the site is secure, you will contact Central so a transport caravan can arrive, and medically assess and extract the scientists. They will also sweep the area and assess the situation before sending payment to you. You have just finished a meeting with Regional Security Officer Valius Taver in Synthsky Central, and are walking towards the hangar bay where your BIOMECHs are waiting. You turn and walk down a wide hallway, painted pale gray and lit in a cold light. The far end opens into the hangar bay, and near that end is a door into the requisitions office.

I mean what I say, you can see every step along the way! Aside from some initial early, early idea docs that aren't anything usable for playing the game and don't really represent what it has become
BIOMECH alpha versions ready to download on an itch.io page

If this hits 120 reposts, I release the itch page early with a download to the most recent version. Pre-alpha release and you don't have to pay shit for it, you get a .zip with .docx files and that's the game. (:

also, despite this being a TTPRG, friends kept making the comparison to 90's game boxart. I was provided the layers to the piece, so there are minor adjustments to make it fit the format.

Just a for funsies bit, I am not making a video game!!!
Cover art modified to fit in a ps1 cover art format

Just a couple looks at steps along the way to the final piece.
We have the initial ideas for the cover, and then the first coloring of the cover we decided to go with. It was always a treat to see this shape into what we have
3 initial concepts for BIOMECH covers, with 1 being the direction we went 2 has the bipedal BIOMECH cornering the tripodal one, and 3 has the Biped jumping at the other first color pass of the cover art

HI! Been a minute, been real busy with life.
Great news, there has still been lots of progress despite it all! V0.5.2 was tested, and v0.5.3 is mostly complete!

I'll tell ya what is complete though...
The cover art!
Cover image for BIOMECH TTRPG A tripodal BIOMECH is midair, jumping away from and firing at a bipedal BIOMECH wielding a Ripblade. the Bipedal BIOMECH is bleeding from multiple gunshot wounds. The duo are fighting in an industrial area, with steam towers looming in the background

I also had a tester note how there wasn't a place to learn about species in the game, so I wrote quick blurbs for everyone that can be found in one place. These aren't final, but this is what things are like for now.

Species Human Humans are not native to SR-A-316, but came to the galaxy looking for opportunity after the contact wars. There are not as many humans as there are A’kesh and Xern, who are native to the galaxy. Blood: 12, Strain: 12 A’kesh A’kesh are four legged creatures with 3 arms. They are larger than most humans, and have snouts filled with teeth. Their body sits on top of their four legs, which are long and end in pointed hooves. Two of their three arms sit on either side of their torso, with the third coming from their chest. A bygone caste system used to rely on how close your third arm was to the center of your chest, with arms at the center being desirable. Blood: 14, Strain: 12 Xern Xern are large isopods, a little smaller than the average human. Humans from earth often compared them to “Roly-Polys” or “Pillbugs” Their plating comes in a variety of yellows, oranges, and browns, with some rare exceptions. Xern do not speak, but communicate telepathically. Modern comms equipment is able to transmit these telepathic messages, but intercepting creature to creature communications is much harder, as Xern are able to select the people who can hear them. Blood: 10, Strain: 14 The Dredge The Dredge are the newest species in the galaxy, and only came into existence after the war started. Very rarely, a Pilot who dies in a BIOMECH is resuscitated by the failing BIOMECH, however, this has some consequences. The Pilot is usually physically altered in many ways, their flesh hangs off their bones differently, they may gain or lose limbs, and their memories range from mostly intact to nonexistent. The ones who do not go mad from the change make great Pilots, as they are part BIOMECH. Research has been done on The Dredge, with it only bringing more questions than answers. Blood: 13, Strain: 11

...have you guys seen character sheets yet? Well, they're function over form, to say the least. They'll shape up as I develop the game, and I plan to work with someone to make them look far better than I could on my own.

Still tweaking the newest version!

A character sheet in BIOMECH. it is comprised of multiple tables in a word document. Different attributes are color coded, and the central white column is the base value of each skill. This is in Alpha, and does not represent the final product

A bipedal BIOMECH. It is large and muscular, with metal plating on the face and chest. The shoulder has a large skull shaped pauldron, and its right arm has a forearm plate and knuckle studs. The left arm holds a curved RipBlade. Intestine-like tubes hang from its midsection. a Tripodal BIOMECH. The legs are sharp and chitinous, while the top half is flesh covered in a metal with tan coating. The skin stretches over tubing under it, becoming more rawer near the chitin. The shoulders are hunched over, bristling with weapons, and the top half of the head has been augmented with a sensor array. The parasite launcher on the shoulder has eyes poking out of its front face.

So, I've been a bit slow on writing due to life trying to set itself on fire anytime I sit for a second and breathe.
HOWEVER, @mechanicalblue.bsky.social has still been making great work on the art for the cover! Here's another step of the concepts for the cover (:

BIOMECH- Heavy Mech A heavyset bipedal BIOMECH. it is covered in metal armor on it's right shoulder, and it carries a blade in it's left hand. What looks like intestines hang from it's midsection, surrounded by chitin spurs A tripodal BIOMECH, wielding an array of ranged weapons. It has a sensor array augmenting the top of its head with cables running back towards the shoulders.

Like I said, @mechanicalblue.bsky.social has been making strides when it comes to this project. BIOMECH now has a proper logo! More to come, but below this I'll post some concept stuff for y'all to look at!
BIOMECH logo The B is comprised of a skull and curved spine, with plating on the side of the skill. The I and O are viscera and gore "MECH" is metallic, plated lettering, spotted with rust

Also, I was talking about weapons? I am getting weird with 'em, here's one: The Blight Cannon
Blight Cannon Damage: 2 Skill: Coordination Attributes: Ranged, Action 2, Burning 2, Disruptor 3, Overheat 2, Pyrexic, Pierce 4 Range: Medium Type: Bio Minor Critical (-15) This attack gains an additional Pierce 2. Major Critical (-35) This attack gains an additional Pierce 2 and Blast 4, any entity damaged by the blast also suffers the other attributes of this weapon. Minor Failure (+15) Jammed. Gain 2 Strain and use an action to un-jam your weapon before you can use it again. Major Failure (+25) Overflow. The weapon overflows, spilling onto you. You suffer the weapon attributes as if you were attacked by the weapon.

Hi, still alive - moving and doing things, even!

Good news: I'm getting in the first test of V 0.5 in tomorrow

Gooder news: @antthonygallego.bsky.social has been doing wonders with concept art, real excited for where we are going! Here's a couple pieces as a sneak peek

#BIOMECH
#BIOMECHTTRPG
3 concepts for heads. Each one an amalgam of flesh, metal, and bone built for war. All of them are humanoid. #1 has exposed teeth and plating covering the top of the head and eyes, the plating goes down the sides of the jaw into a spike at the chin. there is a flange on the back of the head. There are multiple slits in the plating where the eyes are, 3 per eye. Strands of flesh stretch between the lower jaw and eye plating. #2 has plating covering the top of the head and face. This one is a bit heavier than #1, but has the sides of the head exposed. There is a device sticking out of the flesh exposed on the side of the helmet, with wires connecting to various points of the armor. The plating is ridges in a line that goes from where the ears would be, to the nose. each side of this ridge curves under the eyes, coming to a point at the nose. There is a ridge running along the jawline as well. The plating has a set of eye slits, one per eye. Strands of flesh connect the eyeline and jaw ridges. #3 is exposed. This one is the most humanoid, with distinguishable facial features rather than exposed bone and plating. The facial features are instead sculpted out of bone and plating, covering whatever lies underneath, raw flesh peeks out from behind the mask, with milky eyes adding a dead gaze to its visage. The mask wraps around multiple points of the head, connecting to metallic plating in the back. Strands of flesh follow, running from the face to the back of the head, stretching over plating underneath. 3 test stances for BIOMECHS, leaning more towards humanoid features. Each one is a rough silhouette done in greyscale. #1 is almost graceful, its legs crossed in step with the torso facing the camera. The arms come down from broad shoulders, going almost down to the knees. The torso is a ribbed structure, lighter than the rest. it's head is held high, looking directly at the camera. #2 has a hunched over back, its head is lower, almost as if it is looking for something on the ground. it would be taller than #1 if not for its stance. this is a more medium weight, with defined plating all around. it's neck also seems longer than #1. it looks away from the camera out into the distance, searching for something. #3 is stouter, more hunched than #2 - its head almost coming from its chest. it is heavy and bulky, with thick plating covering its body. its legs are reverse joint, with thick, multi-toed feet at the ends. its arms come down from heavy shoulders, past the knees. it looks at the camera, battle ready.

The holidays keep clinging to my ankles and slowing me down, but I had to develop a new weapon just a little early to V0.5.1, cause it really fit one of the new test characters (more on that later)

Anyone else like AC6, btw? Still thinking about that game.

Percussive Spear Damage: Force +3 Skill: Force Attributes: Melee, Reload 1, Pierce 3, Violent 3 Range: Engaged Type: Kinetic Minor Critical (-15) This attack gains an additional Gore 1 Major Critical (-35) This attack gains an additional Gore 2 and Pierce 1. Roll on the Crit Table for an additional effect. Minor Failure (+10) Overheat. You gain 1 HEAT during this attack. This does not count towards the increment for taking multiple HEAT actions per turn. Major Failure (+15) Failed Mechanism. The mechanism to retract the spear fails. Either take 2 actions or use one action to make a Hard Systems check to retract the spear. +2 Difficulty to use any weapons that are not shoulder mounted until the spear is retracted. You cannot use the spear until it is retracted.

Back to work today, and it starts with getting characters ready for v0.5.
Next version is gonna add a lot of additional items, weapons, and mods. Mods are starting on character sheets. here's a peek at the first of many to come.
#BIOMECH
#BIOMECHTTRPG
Reactive Armor Hardpoints: 2 When hit with a ranged weapon, entities within Engaged range must make a Reaction Speed check, Threshold 50. If they fail, they take 4 damage before Soak.

Just so you have something to look at, Burning and Blood Loss underwent a few changes. Both now have more player agency to deal with the issue, but have lasting consequence.
Burning- Entity takes damage equal to level of Burning at the end of their turn. At the end of the entity’s turn, remove 2 ranks of Burning. Additionally, if the entity takes burning damage; remove 1 point of Blood from the Blood pool maximum, and restore this once Downtime has passed. The entity may make a standard Reaction Speed check to bat out some of the flames, and lose 2 levels of Burning. Blood Loss- For each rank in blood loss, the entity loses 1 Blood at the end of it’s turn. Additionally, for every 5 Blood an entity loses this way, its General Modifier suffers a -3 penalty. For every level in Blood Loss the entity has, it is an additional Difficulty, starting at a Standard Systems Skill Check, to close the wound and lose all levels of Blood Loss.

renovating the whole system to make the math easier to track sure takes some fucking time

also, past me couldn't decide on consistently using words. it's great
Discord screenshot, all from user JetmanJay: it isn't done, but I have made a good amount of progress. Mostly language left to do I think? Brain fried, not an official release Attachment file type: document BIOMECH ALPHA V0.5 rough.docx 38.23 KB oh, and the setting and overview right anyway plus, I plan to make a section for the alpha that is about what to expect from the alpha and how to play it
