About the game
Aliens come in from the right side of the grid, and you hold them off with guns you buy using gold. Put matching guns together to build stronger tiers, up to eight in all. Start each wave, survive the bosses, and bring your upgrades into the next run.
How to play
- Click or tap to buy a gun, then pick it up or drag it around the grid. Drop it on a matching tier to combine the two, swap places with another gun, or scrap it.
- Start the wave and the guns fire on their own. Save the airstrike for heavy waves.
- Between runs, spend cores and salvage on permanent upgrades.
