Alternate Weapon Uses
[Submitted by: Cheat Masters ]
Weapons exist for a primary reason to kill your foes brutally. But a lot of them also have alternate uses. For instance, weapons like the machete, meat cleaver, knife and glass shard can cut various ropes you encounter throughout the game. The knife will allow you to pick locks, the crowbar can break open padlocks, and a well-placed bullet from your firearm can eliminate locked door handles.
