Toss an item at the submachine gun to make it fall down. Look up into the tree to see a submachine gun lying on the lowest branch.
Leisure Park: Walk to the far northwest of Leisure Park, to the right of the entrance to the parking lot, and look for the largest tree in that area - which is the middle tree.
Jump to the platform with the Italian mascot/sign the gun is in front of the Italian mascot on top of the "C".
Food Court: Jump on the railing to the left side of the Italian mascot/sign near the south entrance to Chris' Fine Foods. Jump to the slim platform that the columns below are connected to in order to reach the other palm trees. One of the palm trees has three grapefruits and one of them has the submachine gun on top. Frank will grab onto the side of the palm tree. While on the railing, step back one step so that Frank turns then jump to the palm tree in the distance. Stand near the railing next to the palm tree and perform Frank's Somersault Kick move (while standing still, ) to get on top of the railing. Entrance Plaza: Hidden in a palm tree in the southwest. Al Fresca Plaza: Submerged in the fountain along with a Dumbell. There is an achievement for not missing with an assault rifle, which is easily done by shooting all 150 of the bullets into a carcass in the meat processing room. For example, the Lego building with the SMG atop it in Wonderland Plaza works well for this, as do the tops of the shelves in the warehouse. The easiest way to kill them is to rush one with a powerful weapon like the battle axe or katana, kill him, take his rifle, then climb on top of something high enough that they cannot return fire and shoot the reinforcements as they arrive. However, you shouldn't try to use this weapon against the Special Forces soldiers if you are on the same level as them, as their fire will stun you and make it hard for you to shoot back. Its magazine contains 150 rounds which is more than any other gun, and it only takes one burst of three or four rounds to kill a zombie and roughly 30 rounds to kill one of the Special Forces soldiers. The assault rifle is easily the best firearm in the game, and really one of the better weapons overall. Weapons used by the Special Forces that have been sent to clear out the mall. From one of the three survivors in Huntin' Shack, North Plaza.
