The Bren 10 is a weapon featured in Thing-Thing 4.
The Bren 10 is a semi-auto pistol chambered in 10mm Auto, a .40 caliber handgun cartridge whose killing power exceeds the tried-and-true .45 ACP, due to boasting more powder in the casing, which leads to a stronger muzzle velocity. Because of it, it is a very good alternative to other handguns such as the 1911 Custom, 1911A1, CZ-75B, and USP Tactical. The Bren 10 is powerful enough to kill in about three shots, especially to the head. Sure it has as much recoil as the 1911 Custom, but it's muchly covered by the 10mm Auto's power. Project 153 is seen holding one of these guns in the cutscene before the boss battle with him.
