Obviously, running on the CryEngine means Nexuiz looks a lot better than Quake 2. But even that series' aesthetic has come along for the ride, with intricate wall fixtures and tons of gratuitous textures and reflections placed on maps full of ramps and teleports. Lines of shield powerups and the game's nine different weapons are placed judiciously, so that as you fly around the map, you're constantly picking up things and glancing for an opponent running past.
Nexuiz's big innovation (though even this idea borrows from other big-arena FPS games such as Unreal Tournament and Quake 3 Arena) is mutators, which are special powerups that can be picked up an activated at will. There are more than 100 different mutators in the game, and while they can serve as standard powers like extra damage or temporarily invulnerability, they very quickly tend toward the weird and/or wonderful. One can turn off gravity for your character, another will summon minions to fight for you, and others will let you see through walls or even switch places with the enemy team.
There's more: One mutator causes a huge whale to appear on the map (granting a reward to the first team that kills it). "Colorblind" makes the game go black and white for a while. Another, called "Farty Poopy," replaces all of the sounds in the game with fart sounds made by the developers' mouths. As you might imagine, the action is already frantic, but mutators can make it completely insane.
Unfortunately, Quake 2
and its ilk are unapologetically twitch shooters, and Nexuiz
holds that line -- if you like your first-person shooters tactical and realistic, this one's not for you. Playing the game with a controller also causes some problems; while the sensitivity can (and probably will) be turned up, moving a thumbstick around can't really compare to flicking a mouse when things are moving so quickly. And lag could be an issue online as well when things are this tightly wound, but the CES build understandably had some network obstacles to overcome.
The other issue with Nexuiz
might be a lack of variety in the metagame: There are only two 4v4 modes to play, standard team deathmatch and capture the flag. But then again, we couldn't get enough of just blowing each other up back in the day, and for 800 points during Microsoft's XBLA House Party promotion next month, Nexuiz
could be an old school FPS trip worth taking.
