Grenade Launcher

4-1, the statue area of the ruins (Labyrinth): silver briefcase, loaded with 12 Explosive Rounds. Sources place it differently (south-west ground-floor quadrant, or the upper floor of the statue-puzzle room), but all in 4-1. Shop: ₦10,000 (one source says ₦5,000).

Load it for the boss: Flame for the Uroboros and final Wesker, Electric or Acid for Reapers, Acid for Lickers, Flash for Plagas.

• It fires in a straight line and bursts on impact: aim at the floor, at the feet.
• To switch types, combine the other round with the launcher; the loaded rounds come back as a stack.
• It is the only ammo the shop sells, in packs of 12: Explosive ₦4,800, Acid ₦2,400, Flame ₦2,400, Electric ₦1,200, Flash ₦600, Nitrogen ₦4,800. Explosive, Acid and Flash from 4-1; Flame from 5-2, Electric from 5-3 and Nitrogen from 6-3 per one source (another says all three only after clearing 6-3).
• Free: 6 Flash Rounds in a chest in 4-1; 5 Flame Rounds by the Uroboros Mkono door (5-2); 12 Electric Rounds in Missile Area 2F (5-3); 12 Acid Rounds at the Monarch Room Entrance (5-3, not on Professional); 5 Flame Rounds on the Bridge Deck (6-2); 12 Nitrogen Rounds (upper right room) and 12 Acid Rounds in the Engine Room (6-3).
• Acid on a Licker sets up the heart stab (Heart Stopper achievement). Nitrogen freezes, and the enemy shatters to any hit (the Chainsaw Majini resists). Electric stuns like the Stun Rod and electrifies water. Flash one-shots a Duvalia.
