I went for what I hope is a fun and colourful concept with a slight gothic style typeface which I modified using Impact, that I felt would be suitable for many areas of gaming, not only Warhammer 40k and Fantasy. I've included the bomb and tag line as suggested in the brief and also used the burning fuse to create a military generals medal motif that might be worn on a uniform. I hope the picture looks ok. I was really pleased with it in adobe illustrator. Any problems let me know.
