LHFire - Explosion Sprites for Games

When developing shootem-blammo games, one invariably finds that they need multi-frame explosion sprites but unlike stock audio, there's really not much out there, so until you can afford a professional studio to blow things up for you, there's LHFire, available on LordHavoc's Dark Places download page.

Boomboom.

It's a simple and powerful particle renderer that spits out lovely TGAs with the alpha channel intact. The image to the left is the sample 'spaceexplosion', and better looking images (from muzzleflashes to blood splats to hyperspace warps) are easily created with its inbuilt scripting language. Handy pants.
