Crysis!
I think I had a fps toothache earlier this weekend, so I made my mind and eased it with crysis. Its quite similar to far cry, the open ended map design which makes it possible for everyone to choose his own way how to accomplish objectives. An other aspect which I love in crysis is the physics. Almost everything can be broken and blown in pieces or cut down with heavy machine gun fire. The Environment in crysis behaves very realisticly.
In addition this whole suit thing with 4 different combat modes is a blast. Maybe the best thing to come out since the orginal "bullet mode" in Max payne. In the nutshell you wear a nano augmented battlesuit which lets run like a speedy gontzales (speed mode), throw enemies on air, snap their neck with your bare hands, kill the enemy soldiers with one punch, jump above roofs and trees (strenght mode) or become invisible and move undetected among enemies like a predator and take them one by one (stealth mode) and go rambo taking dozens of bullets in your chest and asking for more (armor mode). All these actions drain the suit energy so you'll have to let it recharge itself between stunts and use it wisely.
There are also many different vehicles like jeeps, tanks and assult boats which can be used against enemies. You can do just fine without them, but a machine gun with unlimited bullets gives an upper hand. Simply racing inside the heavily guarded enemy camp guns blazing is tons of fun
Weapons? Quite regular stuff so far..dual pistols, granades, sniper rifle, assault rifles, machine guns..I've heard there are scifi weapons too, but I'm not that far yet. What makes a bit more unique are various wepon mods..silencer, flashlight, laser aim, different sights (scope or iron sight) etc.
Good brains off entertaiment
