Holdout!

Co-op tower defense

Holdout! is a PC co-op tower defense game for 1-4 players, playable online or on one PC. Up to four robots land on a planet full of bugs and try to survive its waves. The robots can’t fight, so you build and supply the towers that do the shooting. The number of bugs scales with your team size.

Making ammunition under fire

You make ammunition from raw ore, then get it to the towers while bugs attack. One player might mine ore, another run the furnace, and another carry rounds and shells to the defenses. There are never enough hands, and bugs can knock robots off their feet, dropping whatever they were carrying.
