About Cartridge Defense
Cartridge Defense is a tower defense game set in a cyberpunk-inspired future, where you use collectible cards to build decks and defend against robots. Play cards, called cartridges, to spawn towers, upgrades, special abilities and other effects.
Build and direct your defenses
Place towers to change the paths enemy robots take, then configure their priorities with customizable targeting systems. As waves advance through your tower maze, your defenses attack them. Each enemy has a chance to drop loot, including cards, packs, targeting systems, items and resources that you can use to customize your deck.
Cards and progression
The game has 9 tower types, each upgradeable to level 5, and over 300 distinct cards. Progress through the story, where levels have specific enemy spawn lists, to unlock cards, targeting systems and playable items. You can also replay completed levels in Sponsored Mode, which uses randomly generated spawns and offers bonus loot.
Game modes and levels
Cartridge Defense has 33 levels across 5 zones, with an expected 30–40 hours of gameplay. It also includes an endless mode and a rogue-like mode.
