Following is a selection of particle systems that I've done using the Unreal Engine 2k4. There are movies next to the thumbnails if you want to get the gist of what they do. They're all blue. This is totally coincidence. The last project that I worked on had a lot of ice and mana which = blue.

When you kill an enemy in melee combat, that enemy drops mana. The players collect it to keep their spells charged.

This is the infamous blood spray. The interesting thing about this system is that it uses collision so the streams convert to splats when they hit something.

If you're going to pick just one movie to look at, pick this one. It uses velocity scales to change the particle direction. In addition, the emitters are attached to movers. It creates a pretty cool pattern. I think this is probably easier to do in Tech3.

This shockwave explodes out from the center as Akila (the player) smashes her fist into the ground. Anyone nearby is frozen. Check out the Akila section if you want to see it in action.

These are twisted sparks. Again, it incorporates velocity scales, acceleration and such. I'm a fan. (Can you tell?)

This is another spell effect. One end of the lightning arch was emitted from the end of Akila's staff and the other hit a bone in the palm of her hand with an event tag like "hitme".

XMen: The Last Stand

Here are just a few of the VFX that I did for "X3 - The Official Movie Game". I did VFX for Iceman, Nightcrawler and Wolverine as well as environmental and combat VFX. I also did lot's of explosions and lasers and shields and...you get the idea (someday I may count them for fun). The game shipped on Xbox, XBox 360 and PS2. These are PS2 screenshots. Oh, just so you know, my favorite is Iceman's shield (#5). It's looks really cool in motion. It's an XBox 360 screen shot.
