Some ideas i think would be nice is firework rockets to give a little more distance of the utility. The Robot idea i have it to make a apoc seeker leave behind a radiated area so it would be a bigger threat then just calling out the the other robots. the mechanics i would thing would be cool is the ability to shot the robots eyes to temporarily blind them for a period of time, wile blind they would shoot wildly damaging there own. Just some thoughts i had wile playing.
