- 1.2.3 - 30 September 2024
Re-added the Just One Character daily modifier to the daily pool A few small bug fixes (including the bugs associated with the Just One Character artifact that made us remove it to begin with!)
- Patch notes- 1.2.1 - 28 August 2024
Temporarily removed the "just one character" daily modifier, as a few bugs have been found with it that'll take a little bit to fix. We'll have it back in the rotation in a week or two. This does mean that today's daily seed has been rerolled and today's daily leaderboards have been refreshed. Sorry about that!
- Patch notes: 1.2.0 - 28 August 2024
CONTENT: Added a daily mode! Everyone playing that day’s daily share a crew, a ship, and a run seed. They also share 1-3 weird modifiers that make daily runs feel pretty different from normal runs! Dailies are scored! Compete with your friends on the Steam leaderboards! Daily runs are available after beating the game, OR by opting in early (and accepting that dailies may contain story/mechanic spoilers!) Here’s a few examples of daily modifiers: One character only! Enemy ship parts are randomly shuffled at the start of every fight! Start with extra health, but most fights take place in Solar Flare events- you’re gonna need the health Cards can only be upgraded to their B upgrade Start with a free boss artifactMISC: Ship health bars now have slightly darker ticklines every 5th tick, to make it easier to tell at a glance how much health an enemy has Made the card “Release” a dual card- yo…
- Patch notes: 1.1.2 - 17 July 2024
PLAYER SHIP CHANGES Ares starts with 1 less hull and 1 less max shield (now 8/4) Tiderunner starts with 1 less hull (now 7/3) Jupiter starts with 2 more hull and 1 more max shield (now 12/4) ENEMY CHANGES Wizbo / The Tower can no longer be in a Solar Flare environment if you entered the fight with 3 or less hull 🧙♂️ 🔥 Janitorbot / CST-7 "Minesweeper" has 2 less hull and 2 less shield Rider / The Solar Sail has 2 less shield X.05 / Rail Cannon puts out a little bit less damage in phases 2 and 3 BUG FIXES / MISC Added a second backup save system just for people whose computers crashed mid-save. Now, if your save is corrupted, you can revert to the backup made every time you return to the New Run screen Fixed a visual oddity where gaining lots of Max Shard would make the status row harder to read X.05 / Rail Cannon now gains 99 Perfect Shield when scrunching and loses it all when unscru…
- Patch notes: 1.1.1 - 28 June 2024
(Lumping the last two hotfixes into this update!) BALANCE CHANGES Solar Sail: one missile intent has been swapped from heavy missiles to normal missiles Rail Cannon: All phases now have 10hp instead of 11 Rail Cannon: All multi-hit attacks now cap at 1x2 instead of 1x3 Minesweeper: on Hardest, gained +3 hull, +3 shields, but is no longer armored (now +2/+2 compared to normal) Replicator: Main cannon starts with +1 damage and can go up to 5 max damage (instead of 4) reworked the card Quantum Quarry's upgrades: Quantum Quarry A now also retains Quantum Quarry B has been completely reworked; it instead gives +1 max shard
- Version 1.1- more enemies! - 17 June 2024
CONTENT Six new enemies: 3 new normal enemies, one per zone! One new elite for zone 2 A new alternate Zone 1 boss A new alternate Zone 2 boss Duncan the skunk, pilot of the Mining Drill, has been upgraded from NORMAL to ELITE enemy. That’s because he kills players more often than any other non-boss fight! Watch out for this guy! One new common artifact: Chaff Emitters BUGFIXES Fixed a graphical bug in the Hardest version of the big crystal fight A few smaller fixes on really weird, niche edge cases MISC Renamed a status from “DRAW LESS NEXT TURN” to “SHAKEN” New splash art by Justin Chan! Look at it!!! Updated credits NOTES In the interest of keeping the game’s initial learning curve the same, all the new enemies can only show up after you’ve played or won a few runs. Pre-existing save files that have already done this will already have access to the new enemies!
- Patch notes: 1.0.7 - 15 May 2024
1.0.7 changes Gameplay The card Escape Artist has been reworked and buffed a bit; it no longer discards any cards from your hand Art Tooth now has a talking animation Misc Fixed a longstanding bug that made the Soggins event incorrectly count as 5 unique events in the event progress bar (whoops!) several dozen small bugs have been fixed the main change: big under-the-hood changes to how enemies work, which should be completely unnoticeable to the average player these changes are the last ones we needed to make for some very cool upcoming content later this summer 😎 If you were in the middle of a fight when your save file was transferred to 1.0.7, the enemy you were fighting might behave a little oddly! Once you start a new fight, everything should be back to normal 👍

- This Cobalt Core mod adds hapless frog Soggins to your crew for extra chaos - 15 February 2024
If you've been enjoying the excellent Cobalt Core as part of this month's RPS Game Club , you may well have stumbled into Soggins the frog along your travels. Running into this hapless buffoon is always a delight in Cobalt Core, as he's one of the few special characters who doesn't instantly attack you on sight. Rather, the task here is always to try and save him from his own idiocy - namely, his malfunctioning ship that keeps firing his missiles right back toward him. He's an ungrateful little sod if you do rescue him from certain doom, but I kinda love him for it anyway - and thanks to an industrious pair of modders, you can now have Soggins join your crew to inflict his own special brand of personal chaos on you.
