Looks like we bagged one, and gave the other a bloody nose!
Same NAV screen as before, but now the "Debatable Merit" is debatably in a better place, while the "Yellow Opera" has massive splash damage to its bow, visible in the lower left SENSORS readout of their ship.

Killing two birds with... four missiles? #gamedev
Ostranauts NAV screen, a blue control panel with buttons, knobs, sliders, LEDs, and screen readouts. In the center of the panel is a large black map with blue, dotted grid lines. Our ship, a blue triangle named "Terrible Tattoo" is firing 4 missiles at two, white triangle, enemy ships at the top of the map: the "Yellow Opera" and "Debatable Merit." The missiles are creating a "V" pattern of red lines emanating from our ship toward them.

"It's just a flesh wound." #gamedev
Ostranauts NAV console, with a variety of knobs, buttons, sliders, and readouts. In the center, a map shows our ship (a blue triangle with gray firing arcs) pointing at a target ship (red triangle and label, denoting that it is marked as hostile) with green trifoil hit indicator around it from our recent railgun damage to it. On the left, we see our own ship in a WEAPONS CONTROL module with a variety of weapons all in green/loaded status. Below that, a SENSORS module shows a white silhouette of their ship with various stats. Notably, almost half of the target ship is smeared with crimson streaks, denoting where our railguns have carved channels into the ship.

Testing out new "pincer" missile path.

We were getting heavy traffic along the line of fire between two ships before, and it was making it a little too easy to snipe a while volley. #gamedev
Ostranauts NAV map screen: a field of black bisected by glowing blue, dotted lines. ZOOM RANGE at the top reads 50.70 km in bright glowing blue. At the center, our ship is a blue triangle pointed downward. It has hourglass-like PDC firing arcs above and below it, and a longer railgun firing arc extending downward, off-screen. A series of scalloped red lines emanate from the ship's left and right side, banking sharply towards the bottom of the screen after about 18 km distance from the ship. Like a giant pincer or caliper. 8 numbered projectile icons are at the head of these red lines. These are the new missile path algorithm in action, firing straight out from the ship a few seconds before turning toward the target.

We're experimenting with letting the user manual-fire weapons outside of auto-target range, for skill shots. #gamedev
Ostranauts NAV UI showing several modules with buttons, switches, and readouts. Notably, there is a WEAPONS CONTROL module showing a white silhouette of our ship with a variety of railgun, PDC, and missle ammo counts in green boxes. There is also a SENSORS module showing a white silhouette of our target, rotated to match their orientation in space. It has several readouts on it for the weapons, crew, thrusters, and sensors they have, and how well our sensors read them. The main part of the screen shows the MAP module: a black field bisected by glowing blue lines. Our ship is centered, with firing arcs pointing both directly at, and away from a target ship bracketed in red. A red line connects our ship to theirs, as well as a red projectile icon beyond them. This is the result of a twin railgun shot the player fired from 500 km away, one of which hit its mark, leaving red marks on the target's silhouette in SENSORS module.

READ THE ROOM
Ostranauts NAV map screen: a black field with glowing lines plotted on it. It is framed in solid blue line, with dotted blue divisions every quarter. At the top of the screen is printed "ZOOM RANGE: 156.91 km" The player's ship is a blue triangle tucked into the top right corner of the map, labeled with the registration ID M-YYW. It has a motion trail behind it toward the middle of the screen, and gray firing arcs point upward. At least a dozen other white triangles dot the middle of the screen, each with a reg ID below them, and red angle brackets around each indicating they are targeting the player. A jungle of red projectiles and their motion trails all reach toward the player in a threatening echelon from those ships.

Snuck onto a ship to crash the party #gamedev
Two-frame screenshot of Ostranauts door breaching via mining charge. On the left, a silver canister with caution stripes and blinking red LED sits just outside a closed airlock, the other side of which is hosting what looks like a party for crew in orange EVA suits. One, a Raphael Travis, is approaching the door, and a tooltip over them says "Planned: Drink." Another is sitting with their back to the door, and there's a progress bar beneath them saying "Can't relax." The right panel shows the charge exploding in balls of bright orange gas. Floor tiles around it have ruptured, the blackness of space visible through the gaps, and scrap metal and debris scattered around. Raphael's EVA has been blown clean off his body, and he lies limp in the now-damaged door with only a helmet and skivvies on. His pocket knife scattered northeast, and a combat knife lies on the floor at his feat. (I guess Raph likes his knives!) The sitting EVA person is now standing up, and some more crew are now visible in that party room, further away from the door.

I think these gray lines are a bug (duplicated orbit lines), but they kinda look nice! #gamedev
Black screen with glowing lines rendered on it. A NAV screen from Ostranauts. The screen is framed in a blue line, with dotted lines dissecting it into octants. My ship (Silent Company), a tiny blue triangle with gray firing arcs emanating from it, sits in dead-center. An enemy ship (Kinetic Paramour), in red, sits in the upper right quadrant. About 2 o'clock. The enemy has a tan circle drawn around it, encompassing my own ship. This is its estimated range to detect me, based on their sensors and my active equipment. Slashing across the screen at a diagonal is a teal-colored line. And a series of faint, gray lines run almost parallel to it in diminishing spacing, making it look almost like one of those "high tech future" commercials from the 80s.

The bigger they come, the harder they fall. #gamedev
Sensor panel in Ostranauts. A dull blue panel frames a black screen showing a ship silhouette rotated to 11 o'clock. It is a white outline of several joined rectangles, filled with a gray color. Blood red swathes are carved out of the middle, as if something gouged clear through it from various angles. Along the sides of the display are readouts about the sensors and capabilities of the target ship, printed in pixelated white font. Along the bottom are tabs for LOCK, VIZ, HOSTILE, and SENSORS, with a hardware button just below each, MFD-style.

Uhhh... I guess the results of the test are in:
Top down view of a large Ostranauts ship. Dim sunlight from the top left casts long, stark shadows revealing the shredded hull of a once-proud Pequod Technical. Entire swathes of the ship are missing, with jagged edges where the railguns chewed holes through it, and stars visible beyond.

Testing the efficacy of railguns. FOR SCIENCE #gamedev
Ostranauts ship design, approximating the silhouette of a tophat, with 6 railguns mounted on the bow, flanked by 2 PDCs. Sensor clusters project out from either side, along with 18 RCS thrusters symmetrically placed along sides. The docking ring is mounted on the aft. Inside, the ship is spartan. Bare essentials for power, HVAC, RCS, and a NAV station buried near the core of the ship. A dead body in skivvies floats outside the ship near the airlock. Leftovers from an earlier "repel boarders with a shotgun" test.

A roving ship battle passing close by in the asteroid field. #gamedev
Screenshot of Ostranauts NAV map, a black screen with glowing blue lines slicing it into a grid. The player's ship is a blue triangle in the top left, with gray, hourglass-like arcs of fired radiating out from it. Lower, in center frame, 3 white triangles are drifting toward the lower left corner, their flight trails curving behind them. Two have the red hazard outline denoting recent weapon discharge. Further to the right, another, smaller white triangles arcs toward the group. Brown circles dot the rest of the map, indicating nearby asteroids.

Stray fire from a nearby ship battle #gamedev
NAV screen from Ostranauts showing a black screen with glowing vector art plotted in it. A gray-blue frame surrounds it, with MAP printed at the top. The screen shows the player ship, a small blue triangle labeled M-538, with a few gray firing arcs. The arcs are barely a tenth of the map's radius of 377 km. From the bottom center of the screen, a dozen bright red lines streak across to the top, narrowly missing the player. Projectile trails tracked by the NAV from a nearby ship battle. Elsewhere on the map, a scattered few dull brown asteroid circles, and one orange beacon marker.

One of our playtesters testing the efficacy of ship armor.

On the bottom hull surface, the new modular armor cladding.

On the top, the signature red frames of Ogiso work safety posters, for comparison :) #gamedev
Modified Rouncy ship in Ostranauts. A tan-colored cabin area and gray engine room, all in warm, yellow light. The bottom, exterior hull of the ship is lined with modular, gray, ribbed cladding. A bit like the armor plates one would see along the treads of a tank. Along the top exterior hull are a similar line of red blocks, representing Ogiso work safety posters.

Working on the conversation logic for surrendering in a ship-to-ship battle. #gamedev
Screenshot of the COMMS panel in Ostranauts. A black screen with metallic blue borders on left and right. The screen is cropped to a short exchange between two ships, printed in glowing blue fonts: "Cease fire! I surrender!" "You're more valuable to me dead." "Here's $1M!" <in green> "You know, I'm feeling nice today. Fine."

When spacers need a break:

"Smoke break!
Viceroy's orders."
Print ad for a fictional cigarette brand in Ostranauts. A seafoam-green , portrait-orientation poster featuring a large, red, anthropomorphic cartoon rabbit with cream-colored belly. They're standing, leaning against an unseen wall, one leg crossed over the other. One arm is across their chest, while the other casually holds a lit cigarette between fingers in an open hand, palm-up. The print reads: "Sungura Viceroys cigarettes," with the V formed by the rabbit's ears. A tilted cream cigarette box below that features a more natural rabbit silhouette in red, with the same "Sungura Viceroys" built around rabbit ears. The bottom of the package reads "Raw Flavour Tobacco: Filterless." Below the box, in black print, "Smoke break! Viceroy's orders." Art by Freddy Frydenlund. https://freddyfryd.com/

Placeholder ore yields for mining in the 0.15 update #gamedev
A wide-angle, top-down view of a spaceship hold in Ostranauts. The hold is made of tan, raised floor tiles, with dotted gutters across some doorways. Matching walls run across the top and bottom of the shot, with the signature white and red striped patterns denoting airlock doors embedded in each. Warm lighting fills the room, and pinpricks of green indicate working appliances. Across the floor, in the center of the frame, are stone-colored spheres with large cyan glyphs and a smaller white stack counter on each. The large glyphs read "Mg," "Fe," Si," "Co," "W," "Ir," and "C." Another shot of a loaded cargo hold, this time in medium gray tile floors and tan walls. A bit of brightly-colored blue and yellow reactor kit peeks out from the top and left of the scfreen. And some air processing, RCS thrust, sensor control panel, and storage bins line the bottom of the screen. The center of this screen contains more of the stones with glyphs from the previous image, but also some reading "H2O."

Testing out faction beacon colors near Ceres #gamedev
Close-up of Ostranauts's NAV map. A black field crisscrossed with dotted lines every quarter, and the bright blue text at the top reads "ZOOM RANGE: 31745 km" In the top right of the map, "Port Mojave" is printed in white near a white diamond shape, attached to a light green circle representing Ceres. A light green orbital line bisects the circle, bisecting the screen towards the lower left. On the lower left side of the screen is another white diamond, with "Zhonghuamen Terminal" printed near it. Between them both are dozens of solid, tan-colored dots in clusters, and a series of icons that vaguely look like the silhouette of Tie Fighters. Icons closer to Zhonghuamen are red, and labeled with "CCRE Beacon," while the others are blue, closer to Port Mojave, and labeled "Galilean Confederacy Beacon."

We might have to reduce the range a bit, too.
Another shot of the NAV screen from before. This time the top reads "ZOOM RANGE 14056 km" and the explosion is almost 25% the diameter of the map. Nearby asteroid clusters are starting to be subsumed by the explosion.

It's fine. Everything's *fine*
A continuation of the previous explosion image. Now the red streaks have expanded past the edges of the screen, and it looks like we are flying into red hyperspace.

I may have to dial it down a bit on the scuttle debris... #gamedev
Close-up of the Ostranauts NAV map panel. A blue panel frames a black screen, split into eights by glowing blue dotted lines. The top of the panel reads "MAP" in white print, and inside the bezel of the screen, in bright blue text, is "ZOOM RANGE: 285.19 km" The player's ship (Storm Semicolon) is a tiny blue triangle just north and east of center, with gray firing arcs emanating from it. Just to the southwest is a massive bloom of 50-60 bright red streaks emanating outward from a point. A red particle at the end of each streak. Barely visible in the hail of debris is a white triangle of an NPC ship, named "Elements of Truth."

What happened here?
On the other side of the thruster and wall, a small, metallic room made of dark, blue-gray metal. Across the room, another wall and thruster mirrors this side, and another bulkhead with conduits is on the right side. But on the left side of the room, a regolith wall intersects the floor. Square fastener patterns are set into the floor at intervals, and a motor and heat sink lie discarded on the floor. Some sort of sensor is built into the right wall, and more room is faintly visible beyond. The regolith wall from the previous image is labeled in white text, now at the bottom right of this image.
December 17, 2025 at 10:01 PM

Hmm. A regolith wall, and... an RCS thruster?
The green EVA suit is now floating just below the three nozzles of an RCS thruster. Its light amber shaft extending upward into a flat, gray-blue wall with some striped, yellow conduit along it. A cluster of small rocks floats just next to the nozzles, and a large, regolith wall dominates the right side of the screen, occluding the stars.

Going to take a look outside the ship:
A wide shot of the void, with a tiny person in a green EVA suit, floating in the lower right corner. Some footprint indicators show that they are heading up to the top center of the screen, where shadowy dark blobs and a few hard-to-discern details occlude the stars. The frame, and glare of the EVA helmet's visor overlays the entire view.
