Gas barrel

Gas barrels are featured in a number of Resident Evil games, and are used as explosives to kill or disable a larger group of enemies. The first appearence is in Resident Evil 3: Nemesis, where they were used against swarms of enemies, and were even used by Mikhail Victor in one possible scene. Claire Redfield uses these barrels to bring down a security unit in the opening cutscene to Resident Evil Code: Veronica. Resident Evil 4, 5 and the Chronicles titles use them significantly. They are set to return for Resident Evil: Operation Raccoon City.
