Core Brigade puts you in command of a base under siege by waves of predatory insects. The central constraint is sharp: only four defensive towers per scene, forcing every configuration choice to count. Across 15 stages — each chapter divided into five levels — enemies grow tougher and more numerous with every round, demanding increasingly careful preparation. The kill-reaction chain is the mechanical heart of the game: towers interact through freezes, blasts, armor breaks, and finishers, rewarding players who think about tower combinations rather than raw firepower. Blueprints and Core Chips carry progress forward permanently, so each run builds on the last.
Before entering a scene, visit the Loadout screen to choose your four towers, then select a stage and place towers on the available open pads. Each level requires surviving 10 waves of attacks with Core HP still above zero. During a wave, built towers can be upgraded, changed, or dismantled on the fly if the front lines are struggling. Speed controls let you manage the pace of combat. Win the scene to earn Core Chips and carry progress into the next stage.
If the base's health bar has not depleted by the end of the tenth wave, the scene is won. If the base falls before that point, the scene must be replayed.
Each chapter is divided into five levels, and each level consists of 10 waves of attacks, for a total of 15 stages across the game.
Yes. During a wave, any built tower can be upgraded, swapped out, or dismantled directly, giving room to adjust if the current configuration is not holding the line.
Core Chips are earned by winning scenes and can also be obtained from free chests or the fortune wheel. They allow towers to be unlocked and upgraded in the Loadout screen before a scene begins, provided the necessary cards are on hand.
Each level becomes more challenging, with enemies growing tougher and more numerous, which requires more careful tower selection and preparation before each round.
