A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Hey everyone! It's been a week since DINO MERCS exited early access. It's been an exciting time and there's still more to come! If you've played the game, thank you so much! It means a lot to me (Tim, the dev) that you would spend your time playing my game. In this post, I'd like to give everyone an update about what's upcoming: Balancing the Game This is my first game, so I will be the first one to admit that I have a lot to learn about game design and balance. I'm continually working on tweaking variables and adjusting how the game plays and feels. You can expect to see regular patches that
Attention all mercenaries! The long-awaited release of DINO MERCS is finally here, unleashing its full glory on Steam! Strap into your boots and join the ranks of Dark Solar Defense to unleash your inner DINO MERC — a battle-hardened veteran ready for action. With four unique characters, each boasting their own skill set, you'll be equipped to wreak havoc on fascist forces like never before. But here's the twist: victory isn't just about brute strength. Master the Card Positioning System to outmaneuver your foes and strategically play your cards to evade chaos. As you build a deck that strikes
I've got some fixes, adjustments, balancing, etc.! Hopefully these tweaks all improve the gameplay experience. There are still a number of things I'm experimenting with, and should be able to release those soon! - Smaller band of effect levels: +3x -2x - Add "none" slot in the middle - Modified damage profiles, but I will likely continue to revisit these - Fixes for Armor Bash & Energy Lash cards - Greatly increase bleeding and toxic gas damage - Increase (double) the effects of all status cards (panicked, dazed, etc.) - Lower all max stats, give characters and enemies lower max defensive stat
Get ready for the BIG BANG! We’re transitioning from early access to full release on 12th of March, 2024! Whether you're a battle-hardened mercenary or a green bean recruit, DINO MERCS is sure to leave you in awe! But before we unleash the mayhem, we've got some bug stomping and meat munching to do. Gotta get that primal vibe going, right? Ha! So sharpen those claws and chomp on that raw meat—it's gonna be a wild ride! Now, let's talk about what's crackin': Strategic deckbuilding: Beef up your deck after each round to outsmart rival mercs. Tactical card play: Utilize your and opponent's cards
I've fixed another handful of things! - Changed Armored Division card to buff character's Max Armor instead of Aim - Fixed Tank Boss title (had wrong affiliation) - Fixed a Hot Zone description that was messing up the typing effect - Dramatically increased the speed text is typed out, sorry it was so slow before! - Fix the render order of the menu on the combat rewards store, so you can actually use it now Next up: I'm going to be doing quite a bit of balance changes. In particular, the power level of enemies and cards will increase at a slower rate, so things don't get so wild so quickly. If
Various players were experiencing some issues that I've now fixed! If you come across anything else, please let me know and I'll fix it asap. If you haven't played the game in a long time (several months or more), your save file may be incompatible. I had to make some breaking changes to save files a while back. So if you are playing for the first time in a long time, and get stuck on the "Unnusual Undertaking" splash screen, you may need to delete your save file or reinstall the game. I'm very sorry about that! I try to avoid this kind of thing but at a couple points during Early Access, the
I know it's been a long time since I've given an update, sorry about that! Well, today I have big news: all the changes, fixes, and polish that have been simmering on the beta/test branch of DINO MERCS are now fully available to all players! This is the last *big* update before leaving early access. So there will be bugs, balance issues, and lack of polish in some areas. Please be patient with me while I clean everything up! From here on, you can expect a number of small patches and improvements. There are a ton of changes in this update. Like, I lost track of all of them. Here's a bunch of th
Got a patch for the latest version of DINO MERCS! Includes these fixes and polishing: Fixed an issue where some common cards weren't unlocked by default, causing a bug on the unlocks screen. Fixed an issue where some stat cards were not being included in Simulated Combat, resulting in some cases where card descriptions were not 100% accurate. Fixed an issue where card descriptions sometimes had wording like "Aim + -12". Now it will be "Aim - 12". Massively buffed Support card passive effects since max stats are so much higher now. When you remove a Support card from your deck, the passive effe
Early Access Release v4.1.0 is live on Steam! This update might not seem like much at first glance, but underneath the hood, there's a lot going on! NOTE: since the game is still in early access, please be aware there will be plenty of bugs, balance issues, and missing things. If you find any of these, please let me know here on Steam or on the discord server! Notable changes: Simulated Combat! Previously, if you looked at a card description, it would tell you its immediate effect. This was slightly misleading because things would perhaps change by the time that card actually resolved. Now, ev
New patch out! - There were some issues with how stat bars for the player and enemy were being initialized and/or updated at the beginning of combat encounters, leading to occasional situations where cards wouldn't be drawn. A few players reported this issue to me, and after this fix, I haven't experienced it again. But, please let me know if it reappears! - Ensure that enemy cards aren't added to the player deck in instances where you might retreat during the enemy turn or the enemy dies during their turn (e.g. bleeding damage). - Some minor UI polish for stat bars Next up, I'm working on a b
2 patches in 1 day! Around 10 bugs down, probably around 200 more bugs to go... This month you'll see a lot of these patches. Again, a big thank you to anyone who finds a bug and reports it via Steam or Discord. It helps me a ton! Working solo on this project means that even if I do a ton of play-testing, I'll likely miss at least a few bugs every time. Here's what I fixed in this patch: - Potential fix for an issue where status cards persist in your deck after a combat encounter, leading to strange bugs and possible soft-locking. I say "potential" because I personally haven't encountered this
Got a few fixes for some things! You can expect quite a few patches over the next few weeks as I fix and clean up things and work on balancing the game. - Potential fix for a soft-locking bug that occurs after status cards are played - Fix bug where the code was trying to remove cards from card pool twice upon purchase - Fix incorrect description on enemy smoke grenade status card - Updated credits, was missing someone
