Perfect Dark Zero

Successfully complete the game on Perfect Agent mode to unlock Dark Agent mode.

When the final Boss jumps to the platform you are standing on, he will lunge at you with his sword. Right before he swings it, dive out of the way. If done correctly, he will trip and fall. Quickly grab his sword from the ground next to him before he gets up and start attacking him with it. Note: The sword can be used to hit three consecutive times by quickly pressing RT(3). If he manages to get away, he will summon his sword back to him. After this happens, just wait for him to jump back onto your platform and repeat the process.

When the final Boss shoots plasma balls at you, just move out of the way. When he teleports onto your platform and starts running at you with the sword, just dive roll out of the way immediately before he swings the sword. This will save you from taking a lot of damage.

Whenever you die, it will say to press Back for debriefing. If you don't press it for a while, it will go into debriefing for you. In Arena | Showdown though, it won't. You can watch your dead body lay there for as long as you want. Zhang Li will still be jumping around on the camera in the top right. Waiting there for 5 minutes will make Zhang Li do a victory dance. He will perform a dance move every time he lands and will jump up onto another platform every now and then. If you look closely, he does the exact same moves some people do in the dance club on Nightclub | Stakeout.

When one player has gotten a weapon that another desires, go to Club: Stakeout on Agent mode. Drop that player's weapon to a second player. Have any one of those players continue through the level normally. If done correctly, the new player can have the weapons in less than three minutes. The faster way through the level is to run in the club after the first objective is complete unarmed, and rush to the very top to Jack Dark.
