Icarus

A NanoBot by PEZ

Probably as lousy as all my other nano attempts...

Download it from http://www.robocoderepository.com/BotDetail.jsp?id=2353

The random movement is quite Raiko inspired. With an idiots way of doing what the MusashiTrick does for smarter bots. The gun is semi-linear. Sometimes I use blocking calls making it do some more unpredictable things. =)
