What are the cheats for smileys war

There are no code cheats, BUT on stages where you can fall off the stage, you stand by the edge, shoot at enemies, then when your health is running low jump off the edge. Jumping off the edge does NOT count as a kill for the enemy team. I used that strategy to beat the last challenge of the game, "Hell", 1vs3. Won by 2 kills. NOTE: This only works for the "Team Deathmatch" function.
