What is Variables 2?

A single-player tower defense roguelite where you place your core and enemy entrances, then use tiles, buildings, and terrain to shape enemy routes. You combine basic towers into advanced ones using recipes and equip them with gear that changes their stats and abilities. Before each run, you can plan which equipment and plug-ins to acquire.

For you if...

+you enjoy experimenting with builds over repeated runs
+you like demanding strategy focused on careful preparation

Not for you if...

−you prefer simple rules without recipes or equipment management
−you want cooperative or competitive multiplayer rather than solo play
