Quake 4 is a first-person shooter where you fight the Strogg, a cybernetic alien race threatening Earth. You're part of a marine squadron assaulting their home planet after humanity's first strike only wounded their leadership. The campaign mixes solo firefights with squad-based missions, featuring vehicles like mechs and hovertanks alongside standard FPS gunplay. Mid-game, the story takes a turn—you're captured and partially converted into a Strogg yourself, which changes how you interact with their technology and environment. Weapons range from machine guns to alien energy tools. Levels alternate between industrial Strogg facilities and war-torn outdoor zones. If you want a military sci-fi shooter with body horror undertones and vehicle segments breaking up the shooting, this delivers that specific flavor.
