Mortal Kombat: Shaolin Monks

To fight Ermac in the game you need the swing and wall run ability. simply go to the warrior shrine then use the wall run ability on the wall to your left. Then use the swing ability and swing across the poles then interact with the shrine and it will open the doors. Go across the bridge and u will find statue of the greatest fighters. Interact with the last statue on the left about three to four times and it will eventually shake and crack open. then You will begin to fight Ermac who is very hard because he throws you around the whole shrine

Enter the Living Forest and continue a little bit on until you reach the first save statue. Walk a bit towards the screen and you should see a branch above you. You need the swing ability from the Dead Pool to swing to another branch and then on to a ledge. Jump up and grab the ladder. Climb up and you'll reach a hidden area. Continue on crossing the bridges and fighting enemies along the way if you wish and eventually you'll reach an area with a portal in the back. A cut-scene will begin and you will face Mileena with two other Masked Guards. Take out the guards before you concentrate on Mileena. You get some experience for killing her.

For free health in Ko-op mode, activate the save point multiple times. Each time you activate the save point, your health will increase. You don't have to save each time you activate it for this to work. You can get almost full health from doing this many times.

In the Wu Shi Academy stage (in single player mode) play to the part where Cage opens the armory for you. Instead of going and getting the bladed weapon and the health increase, stay in the area with Cage. This section infinitely spawns Tarkata in groups of three. You can combo one, Fatality another, and finish off the third with Cage. You can build up a decent combo and every Tarkata you Fatality gives you over 500 experience. You can max out a character fairly quickly, and this is only the second stage of the game!

In Ko-op mode, go to the Living Forest and go to an area with clay golems. The best area is probably at the door in the area with the waterfall (right near the door that leads to smoke). Kill or knock away one of the golems and try to leave the other one unharmed. Now, without destroying the unharmed ones shield, trap it against a wall and have both players keep tapping an attack button (X works the best). The golems shield will not break and it will not lose any health. As long as both players are attacking the Ko-op points will keep going up. After every 10 ko-op points both players get a larger and larger experience boost. Just keep attacking and your experience will never stop going up.
