I haven't played many split screen games, but I know this isn't common.

The graphics were awesome (big screen hd tv helped), there was just so much of everything to look at, and a second person can actually be the navigator (especially on levels like Cortina!)***edit 02-11-

Split screen, linked or online co-op

And, Warhawk supports split-screen online, which means you can have 4 people playing in your house split-screen on the same TV while you all play against up to 28 other players online!Compared to these multiplayer games, Halo 3 SUCKS.

a great fps for split screens, most other fps has limited split screen

Some people are kinda stuck up about how H:R and H4 are better
