Fortified

Fortified is an explosive strategy shooter in which players defend Earth against a menacing Martian invasion in the 1950s. You take on the role of one of four pulp-inspired heroes who battle swarms of fearsome robots with an arsenal of Cold War-era weapons and experimental technology. Protect the city by building a network of defenses, commanding an army, and engaging in battle against dangerous attackers clawing from the sky. Fight alone for Earth or with up to four players for the ultimate co-op defense experience.
