Shadowrun

To prevent things becoming familiar, tactics and teamwork are brought into play by co-op skills and complimentary powers, with players able to resurrect downed pals. And since you don't spawn until the next frantic round and reappear shorn of all your between-battle bought weaponry and magic, survival and kills are both currency you need to be flush in.

While the Halo -style shooting system seems to level out some of the inequities of mouse versus pad control, we are still waiting to see if a shared battlefield and the presence of only two round-based modes won't leave 360 gamers gunned down like noobs by PCers.
