Enigmata: Stellar War is an action-packed defense game set in space! Defend your base by building units that will automatically attack enemy spaceships. Once a unit has been built, you can move it anywhere on the screen. Building a unit doesn't cost you a thing, but there is a limit to how many units you can have on the screen at once. Increasing this limit, unlocking new units, and purchasing upgrades requires gold, which is released by destroyed ships and collected with your mouse. You can also build drones that will assist you with collecting gold.
