Quake 4 demo

Quake 4 demo is an interesting game in which players have to detect an army of elite soldiers in a battle against an invading alien race. Earth assumed the destruction of the Makron would end the siege of the cybernetic Strogg, but it didn't. Quake 4 begins where Quake 3 leaves off. The Strogg are quickly regrouping. However, with the Strogg's planetary defenses still destroyed, Earth's forces can deliver a full and final assault. This time, you're not alone. You are Matthew Kane, an elite member of Rhino Squad, and part of Earth's next invasion wave. An army of soldiers are fighting with you and an arsenal of weapons and vehicles are at your disposal in this heroic and epic battle between worlds.

This official demo for Quake 4 lets you battle through two large areas of the single-player game, including a heavily guarded Strogg installation and the chaotic air defense trenches cut through the desolate Stroggos landscape. This demo also features a multiplayer component, with two versions of the map "The Fragging Yard" for three different online modes.
