A bullet-hell roguelike survivor with wild weapon builds, co-op missions, and endless swarms of creepy crawlies in a colorful post-apocalyptic cartoon world. Become a ruthless bird-assassin and blast through insect hordes to stop total bug-geddon!
Bird Them Up
SteamWelcome to a post-apocalyptic world where humanity has long vanished, and the last line of defense against swarms of mutated insects is… birds. You are one of these battle-hardened survivors, and your mission is to carve a path through endless waves of enemies, collecting powerful upgrades, combining weapons, and crafting wild, unpredictable builds. Survive the most chaotic moments — that’s where the best stories are born.
This is a fast-paced roguelike survivor with bullet-hell elements, where every run is a new challenge and a fresh chance to assemble the perfect combo of abilities!
Hordes of enemies, dense attack patterns, and ever-growing chaos — everything ramps up with each passing minute.
From basic bugs to elite mutants and gigantic bosses, every creature pushes you to react faster, think sharper, and adapt constantly. Each enemy type has its own behavior, threat patterns, and nasty surprises, ensuring that no two encounters ever feel the same.
Collect weapons — melee or ranged, light or heavy, technological or ballistic — and turn them into devastating engines of destruction.
Every weapon features its own attack style, unique stats, status effects, and progression paths, enabling dozens of possible builds.
Mix upgrades, stack perks, enhance your movement — your build can become so absurdly powerful that nothing but ashes will remain of your enemies!
Every few minutes, the game throws special challenges your way: infected zones to cleanse, control points to capture, worm attacks, and other unexpected twists.
Each event demands a different approach — move in sync, defend key areas, or make rapid decisions under pressure.
Complete these challenges and claim valuable rewards!
