Glitch: Forest level fires:
Get a bazooka, then find a location in the forest where there is a small gap between some trees. Shoot straight, without hitting a tree. Three or four trees will ignite even though the shot missed them.
Glitch: Stuck in a box:
Start the game in the Blue Spy level in mini-mode. Immediately before the door to the building, turn to your right. You will see two boxes on top of each other. Try to jump on the top box. You will fall off. Keep trying and you will eventually end up inside the bottom box with no way out.
Find three or more boxes that are stacked on top of each other and are blocking a path. Go to the boxes, then hold Analog-stick Up and hold A. While you are coming down from your jump, you will get stuck in mid-air.
Glitch: No shot zone:
There is a house after the first door in the Showdown level where you can walk and the enemy cannot see or shoot you. Do not try to shoot while you are inside, because you also cannot hit the enemy. Be careful if you are using an explosive weapon.
Glitch: Run across water:
Enable the "All Weapons" code. Begin game play in the Blue Spy level and quickly switch to the sniper rifle. Hold R and aim at the blue spy across the water. This must be done quickly as he will walk out of your sight very soon. After you aim , shoot him until he dies. The failed mission message will appear. However, as soon as the message appears you can run across the water.
Glitch: Stuck in Plastic Wrap box:
In the Kitchen level in multi-player mode, a player can get stuck in the Plastic Wrap box.
Glitch: Die with full health:
You can die with full health in any level. Get a health kit and get hit at the same time. You will fall and the "Good to Go" message will appear before the mission finishes unsuccessfully.
