Well, The Hulk is back and free, roaming the streets of San Francisco. He must fend off advancing tanks and helicopters by smashing anything that gets in his way. Smash everything before the time runs out and the Hulk changes back into his human alter ego, Dr. Bruce Banner.
Smash buildings to create as much damage as possible.
In Quake II, the brutal Strogg attacked Earth, looking for fresh ways to re-supply their cyber-organic army. A lone marine broke through their defenses and defeated their leader, the Makron. The Strogg built a new Makron, however, and in Quake 4, you must join the invasion of the Strogg homeworld, where humanity’s only hope lies in your ability to access the highly-fortified structure containing the Nexus Core. There, you can disrupt all Strogg communications and give the marines the upper hand.
