South Park: The Stick of Truth -
Take a shot at the grenade of the dad soldier. Walk through the passage that the explosion created and collect the chinpokomon. Then, summon Stan and use Buddy Command on the rifle, to neutralize it. Alternatively, you can use the probe to reach the valve, shut off the water and teleport into the pipe, where you need to shoot at the wires to make the lamp fall down, onto the rifle. After the rifle is activated, use the Cup-a-Spell on it. Then, go ahead. You will be attacked by a group of zombie fetuses. Apart from the fact that, just like the regular zombies,, they are invulnerable to being Grossed Out and to fire, they can heal themselves, on a regular basis. The best idea is to use a powerful mass fire attack. The buddy that can work well here is Cartman. Then, exit. There you will have to fight a final boss. It is two enemies in one, a fetus and umbilical cord. The cord can heal itself, on a regular basis so, ignore it and focus on the fetus. What works best here is the strong melee attacks. Also, Kenny's Charm or Butters' Professor Chaos will prove their worth here. Once you manage to bring the fetus's health to zero, you will automatically win the fight. The only thing left to do now is return to the girls.
