developed for the marvelous raven software (Hexen, Heretic, Soldier of Fortune, etc.) quake 4 is the direct sequel of quake 2, the story continue the desperate fight of the humanity for survival against the insidious conqueror race known as strogg, who want defeat the human race for one of the most important natural resources of the earth, the human himself. the single player mode begins a few hours later from the operation overlord (quake 2), the Strogg received a hard hit that reduced their defences, one hero, a marine whiout fear, fought against hordes of monsters and destroyed their mayor defense system and defeated their leader. the human race needs to take this opportunity to give us a chance of surviving. now you are Matthew Kane one marine who has the mission to fight in the heart of the enemy planet... and it seems that things will not be easy at all. Several monsters of quake 2 will make their appearance is this game and you will recognize them instantly. Graphically the game uses the ID Tech 4 engine (doom 3 classic), that replaces the orange color from quake 2 for a dark and claustrophobic one, the gameplay, although is run and shoot like every quake title is slightly slower that is centered in the terror, in the game where added some aspects like scripted scenes that give a more cinematic touch, there is few moments when allies can help you and there is phases of conduction too, where you can drive tanks and mechs!, the multiplayer mode, turn on some technics like bonny hopping, rocket jump, etc. giving Q4 a classic feel. The only problem that I have found is from the limitation of the engine for exemple the corposes disappear a few seconds after the dead and the game it feels linear and has few secrets but that does not mean that it is not a masterpiece. thanks GOG and Bethesda for bringing more titles like this!
