Red Faction

Note: All weapon-related trophies count across all saves. If you want you can make a save near enemies, kill them, reload the save and repeat the process for every trophy.

The Fusion Rocket Launcher is one of the late-game weapons and is dropped by mercenaries. This weapon is extremely powerful and has an insane blast radius. If you are within 10 metres of the explosion, chances are you will die. This is both good and bad, as it means you can clear out entire rooms easily but also run the risk of killing yourself in the process.
