Tommy Gun means he will fire off quick rounds of bugs, Snake should duck under the water or wait behind a rock for this attack to end.

The Pain has a number of attacks to look out for. Grenades are useless, because the wasps will pick them up and carry them back to Snake. The weapon of choice for this boss is the AK-47 which damages him when he isn't covered in wasps. Staying in the water is a good bet because it allows Snake to duck under most of the Pain's attacks. The best way to fight this boss is a slow and steady routine, fighting him from the water. At the entrance to the main corridor, check to the right and there is a Medpack. Continue through the tunnel and there is some more AK-47 ammo. Crawl under ledge behind the shotgun to enter a tunnel and go through a room which has the Snow Camouflage. The next set of caves has a corridor to the right which yields the M37 shotgun. Return to the waterfall room once more and this time, stay oh top of the waterfall and enter the hall to find more AK 47 ammo and some Bug Juice. Continue through a tunnel across from this tunnel to come out on a ledge holding the Night Vision Goggles and AK-47 ammo. This leads to an opening that has serum and a c-med pack. Return to the waterfall room again and head towards the batteries, but this time stay along the wall to find another tunnel. Now walk through the tunnel across from the torch and find a battery and some more ammo and walk in a circle back to the tunnel that Snake must crawl through. Underneath the waterfalls there is a Torch. Now, crawl through the tunnel into a room with waterfalls. To the right of this there is a tunnel that reveals a skeleton, a grenade, and ammo. Return to the watery room at the entrance of the underwater tunnel, return to land and walk to the room with the above water tunnel that Snake has to crawl through. This leads to a dead end, but reveals a Ration. Follow the cavern to the water, and swim to find an underwater passage. The floor is covered with nutritious Crabs that can easily be found by putting on the Thermal Goggles. After the battle, Snake fall into some caverns that are filled with water.
