The Aquagrenade, like the Needle Gun, can only be used by Regina in the underwater areas of the Third Energy Facility. In one room, it is required to destroy a concrete pillar preventing the player from progressing in the game. It is also highly recommended for killing the giant Plesiosaurus boss at the end of the area.
The Aquagrenade is also the most effective weapon against the Mosasaurus, requiring only one shot.
Performance: Attack-70, Speed-30, Range-10.
- The Aquagrenade is one of three weapons that must be purchased in order to progress through the game, the other two being the Flame Launcher and Chainmine.
