Whose bizarro idea was it to take a pissed-off Native American, load him up with heavy artillery, and whisk him back in time to an age when T. rexes still roamed? Well, give that guy a medal! In the sickest shooter this side of Xbox killer app Halo, you stay alive by plugging every dino that moves, with a superweapon that features a retina-frying nuke and a remote-control spider that explodes on command. Youll also confront heavily armed lizard men and fly missions on the back of a pterodactyl as part of an epic fantasy story that might even make sense if we bothered to figure it out. So trade that science textbook for a grenade, and get ready to kiss Jurassic good-bye.
