DRW Machinegun

The  is a weapon in Dead Rising. The is used by the special forces that have been sent to clear out the Willamette Parkview Mall. The  is easily the best firearm in the game, and really one of the better weapons overall. It's 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. However, Frank shouldn't try to use this weapon against the Special Forces soldiers if Frank is on the same height level as them, as their fire will stun Frank and make it hard for Frank to shoot back.

The easiest way to kill the Special Forces is to rush one with a powerful weapon like the battle axe or katana, kill him, take his assault rifle, then climb on top of something high enough that they cannot return fire and shoot when reinforcements arrive.

For example, the Wonderland Plaza Lego building with the sub-machine gun atop it in works well for escaping special forces, as do the tops of the shelves in the Warehouse.

Perfect Gunner achievement
To receive the Perfect Gunner achievement in Overtime Mode, Frank must fire all 150 bullets from a Special Forces machine gun without missing. This achievement is easily done by shooting all 150 of the bullets into a carcass in the meat processing room.
