Half-Life 2

Meanwhile, Gordon Freeman, the man who was at the center of the events that took place shortly before the rise of the Combine, awakens from his stasis and is inserted into a train to City 17 by the mysterious G-man. Gordon is soon brought into a resistance group and makes a seemingly futile attempt to bring down the Combine and liberate the Earth.

Gordon's enemies, apart from alien wildlife which found their way to Earth, are mainly Combine forces, which utilize a variety of firearms, gadgets, and vehicles. Policemen and foot soldiers work along with helicopters, gunships, and gigantic walking machines to hunt him down. To defend himself, Gordon has a range of weapons available: from the iconic crowbar for close-quarter fighting, through pistols and rifles, up to grenades and a rocket launcher. One of the most notable weapons is the gravity gun, with which Gordon can pick up objects, hold them in the gun's anti-gravity field, then hurl them at the enemy with great force.

Setpieces in the game include coordinated assaults on enemy bases, fighting gigantic boss enemies, bringing down aircraft with the rocket launcher, and others. A few levels require the player to navigate buggy-type vehicles. Some of the more exotic stages involve the player summoning an army of antlions to unleash on unsuspecting foes.
