Successfully complete the game to unlock the Big Boss Extreme difficulty.

Replay bonus:
————-
Successfully complete the game, and save when prompted to create a cleared saved
game file. Start another game session, encounter Metal Gear II in Act 1, and
load the cleared saved game file to get your Drebin Points, weapons, ammunition,
items, and special items from your previous game.

Alternate ending:
——————
If you fight Mantis with a Sixaxis controller, the ending is different than if
you were using a DualShock 3 controller.

Infinite Drebin Points:
———————–
First, acquire the drum can. You do this by finding the soldier that is hiding
in the can, and using it as a bathroom. After that, go up ahead a few feet,
where you will see three crates. When you have gone past them, you will see just
two crates. You will also see about three rebel soldiers fighting. One is
carrying an RPG and the other two have machine guns. They will die and respawn
continuously. You will have a chance to pick up the RPG after the soldier has
died three times. Do so because each RPG is worth 6,000 Drebin Points. The
important thing is to stay anywhere behind the two crates, otherwise the trick
will not work. Going further than the two crates will stop the respawning loop
of the soldiers dying. The only way to get the RPG without breaking the
respawning loop is to use the Mk II.

Cheaper Drebin prices:
———————-
Set the PS3 system date to a Wednesday or Sunday, and Drebin will have cheaper
prices. Additionally, all of Drebin’s prices are cut by 50% during Act 5.

Extra battery:
————–
Save the game during Act 1. Go to the Mission Briefing screen, and select the
saved game from Act 1. Press Square to control the Mk II while on the plane.
Move the Mk II upstairs, and search for an extra battery. Collecting it will
double the operating life of all battery-powered devices in the game.
