Fire
The gif quality isn't great but here is what fire will look like in the game. I used a rehashed version of the blood splatter shader for the flames, my particle based distortion camera set up, and a fancy trick with my lighting system to make the flames emissive.
The next time you think "I wish I knew how to write shaders", I recommend you take the time to learn them. This crazy looking beast is just the combination of several simple shaders (and a little bit of knowledge of what makes a particle system look nice).
