Hints

Zhang Li Boss Tip
An easy sure-fire way to whack this guy is to take a DEF-12 shotgun and any other weapon that is fairly accurate at long distances (any assault rifle or sniper rifle). Zhang Li will dance around the arena and rain on Jo's pretty young butt with death plasma. Evade the shots using Jo's dodge and when you have a clear shot, feel free to shoot back but only if you are sure of a hit.

Damaging the boss enough prompts a shift in attack pattern, and Zhang will hurl obstacles that are difficult to dodge due to the size involved. Simply go to the far end of the platform when Zhang is lifting the object and run (normally) to the other end when the object is thrown.

Continue the attack on Zhang and this prompts him to jump down to Jo's level and attack with the ViBlade. To counter this, dodge and Zhang will falter, dropping the weapon. Normally, you'd take the sword and hack, but it is better to shoot him full on with a double blast from the DEF-12. Zhang will begin his regeneration sequence once he jumps back up. Shoot him with the long range weapon to stop his recovery process and Zhang falls back into the ring. Now take the ViBlade and start the hacking and it should be able to finish him off (or at least do serious damage) before he repeats his pattern.

HAWK Shield On Vehicle
Jo must have the Hawk weapon unlocked for those vehicle stages. Include it in her kit and head for the vehicle. Stand next to the vehicle and throw the HAWK weapon as far out as possible. Before it returns, board the vehicle and when the HAWK returns to Jo's atavism, pressing RB will activate the ballistic shield while Jo is riding.

Glitch:

Friendly Fire Off (Ranked Matches)
When creating a ranked game select deathmatch "dark-ops". When the scenario is highlighted, hold LEFT on the D-Pad while pressing GREEN. Cycle through until Eradication is showing again. Friendly fire should now be off. (Unverified)

Underwater Exit (Fatal)
Start off Mission 7. This will be much easier if you do it on Agent. As soon as you start off against the Brothers, go down one floor so you're on the left side of the boat. You'll see these columns that you can take cover behind. Go up to the second one and take a gun without a scope, (Magnums, CMP-150s and Uzis work best) and press LEFT-TRIGGER, A, A really fast behind cover.

Soon you will enter the wall, and you then press LEFT-TRIGGER and A and COMBAT ROLL into the wall. This will send you underwater, allowing you to se the Trinity Base from the outside. Underwater. With no air supply. And you don't die. UNLESS you go to far off the rock ledge you fall on, in which case you will fall out of the map to your death

Easter Egg - Jack Dark's Gun
Unverified. Go to the very first level in the game. Play through it as normal until you get in that elevator takes you to the surface. As soon as you get to the end of the elevator ride, you will see Jack Dark (the guy with the magnum). As soon as you see him, free 1 slot in your inventory and get your fists up (up on the d-pad). Go up to him with your fists up and press secondary fire (RB) to steal Jack's gun (His gun is no different than a regular magnum except it has a black handle, a black barrel, and 200 ammo instead of 75.).
