About Fortified
Fortified is a strategy shooter set in an alternate 1950s, where Earth faces a Martian invasion. You defend cities from waves of mechanical attackers by building defensive structures, commanding an army and fighting with Cold War-era weapons and experimental technology. You can play alone or with up to four players.
Defend Earth
Choose one of four pulp-inspired heroes and fight swarms of robots, including dangerous attackers that tower over the city. The heroes include a jetpack-piloting heroine, a shotgun-wielding space cowboy, a secret government agent and a battle-hardened Marine captain. Fortified combines third-person shooting, real-time strategy and tower defense.
Build and fight together
You fortify your base with a network of defensive structures to stop the incoming waves. In co-op, players coordinate their strategies and work together against the Martian machines.
