The leaping innovation in this shooter is that players can control all four main characters, switching from one to the other throughout the game. Position the sniper in a lookout tower, then activate the assault trooper, and the game’s artificial intelligence instructs the sharpshooter to supply ground cover while the trooper goes about his business. Leading men into combat was never so easy. So why is Brute Force such a dud? Well, the elite unit’s top secret missions are as one-dimensional and repetitive as their foes. And the four commandos — two shapely women, one burly man, and a frog beast, cloned anew each time they die — utter lines that would have sounded cheesy even on a ’70s cop show. Let’s hope someone takes Brute Force’s DNA and clones it into a better game.
