Oddworld: Soulstorm

There are many opportunities to obtain this trophy but you'll likely get it at the first chance you get, which is early in Level 2: The Ruins. You will see a Slig walking near an open flame and will be encouraged throw a brew bottle at it. You can either throw the brew at the fire as the Slig walks right next to it, or you can throw brew on the Slig and then throw more brew on the ground, creating a trail for the open flame to follow, Die Hard 2-style. The choice is yours.

As you play through the game there will be many more opportunites to do this, using flares or the flamethrower to ignite the brew if necessary.
