Play Defense Online

Defense was part of the 0 MS-DOS Classic Games collection, a compilation that brought together several early titles from the platform's formative years. It was a straightforward, no-frills arcade-style game typical of the era, focused on a single core mechanic without much narrative or graphical complexity.

You control the placement and firing of stationary turrets to stop an endless march of invaders advancing from the top of the screen. The main objective is to survive as many waves as possible by managing limited ammunition and optimizing turret positions before each assault begins. Key mechanics include choosing where to place your guns at the start of a round and then manually firing them until either the wave is cleared or your base is overrun. The pacing is relentless; early waves lull you into a false sense of security before the difficulty spikes dramatically. It feels like a tense race against depletion, where every shot counts and mistakes compound quickly.

Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
