WarCats

Newest update: Bots ride along (2026-10-11)

• Bots now hop into the passenger seats of a vehicle a teammate is driving, ride with you, shoot from their seats, and climb out when you stop at the zone, when you get out, or when the vehicle is wrecked. They never take an empty vehicle or the wheel.
• Enemy bots now check a prone soldier's real body shape when looking for targets, and their rounds stop at walls, sandbags and ridges instead of passing through cover.
• Includes all recent dev updates since the last release.

Earlier update: Vehicle collision fixes (2026-10-11)

• Vehicles no longer hurt teammates or take crash damage from hitting soldiers. Running over enemies deals damage reliably. The quad is tougher: 340 to 460 health.

Earlier update: Team switching, war map, team merchants, audio pass (2026-10-11)

• Change sides mid-match with M: a live war map you can drag and zoom, with the objective marked.
• Each base's armory now has its own team's cat. Lynx are red now, with red bands on their uniforms.
• Guns sound more distinct and quieter with distance, vehicles are louder, and a headshot lands with a dry thud instead of a chime.
• Support-hand grip and muzzle flash refined.
• Fixed: a gun swapped between backpack and hands could turn into the gun you were holding.

• @neitantei · loved it · 2026-10-11 · played 12 min: “Cute cats causing chaos lmao 😂 The game is really fun, with enemies and gunshots coming from every direction. It's absolute madness! I also love that there's an armory where you can buy upgrades.”

• @chizkeykkk · loved it · 2026-10-11 · played 37 min: “This game is chaotic! haha I like being the sniper of the team as they conquer each place.”

  • @chizkeykkk replied 2026-10-11: “Played this again, but this time with a friend, and it was fun! 😂 Especially when you’re playing as a sniper lol 🎯”

• @makeriffic · loved it · 2026-10-11 · played 46 min: “I like how in depth the gun customization can get. This is now my favorite gun, the MK46 LMG paired with these attachments especially with scope and extended magazine. This kit can reap an entire team on it's own. I hope more guns are added in future”
