Here are some designs for a tower defence game I was working on. Sadly it was aborted, which was a shame as it played pretty well.
Here are some goblins, the typical troop character of the game. I was going for a cute but deadly vibe.
This ogre would be the more defended muscle character. I was messing around with textures but the sprites would have been minuscule in game so you'd have never seen such detail.
I really like this mangy feline warrior. I don't think anyone else on the team did though.
The most fun was designing traps for the troops to blunder into. The garden level was a particular favourite.
