I have been playing through Dynamite Heady and Alien Soilder looking for some cool ideas, but haven't come up with a solid concept yet.
Also, I have starting messing around with Fruity Loops to get my "skills" back up the speed. Fortunately, I came across this today, so I will probably use it for the sound fx ( cause I certainly wasn't looking forward to synthesizing them )...
Should have some concept art up next week.
