Heavy Fire: Shattered Spear

PLAY THE ENTIRE GAME WITH FOUR CONTROLLERS if you got them. The difference in difficulty between using one controller and four controllers is like the difference between Lindsay Lohan and a life long nun. One is as easy as can be and the other is tough and rigid.

One other tidbit: Plug the four controllers in before launching the game. Sometimes if you turn them on while in the main menu it won't acknowledge controllers 2-4.

If you have play THE ENTIRE GAME with 4 controllers, starting using your pistol right away on level 2, and get all the collectibles on the first go, your looking at 3-3 1/2 hours for the full 1000.
