Xbox 360 - Quake 4 only £9.95 (delivered)
* Cheapest I can find it *
Quake 4 is the first game to utilize id Software's revolutionary
Doom 3 technology. In the game, you are Matthew Kane, an
elite member of Rhino Squad and Earth's valiant invasion
force. Fight alone, with your squad, and in hover tanks and
mechanized walkers as you engage in a heroic mission into
the heart of the Strogg war machine.
But, in this epic war between worlds, the only way to defeat
the Strogg is to become one of them. Battle through early
missions as a deadly marine, then after your capture as a
marine-turned -Strogg with enhanced abilities and the power
to turn the tide of the war.
* Another xbox360 game for under a tenner - at this rate 'll never use my PS3 lolz.
