Well, to get an unbiased challenging system going, I'm running every single bot against every other bot, and the winner gets a point. This way there won't be some powerful bot rooted on 20th because 19th place uses some rarely-used defense system that prevents any other bot from entering the league.
Since my last post, I was able to finish 3 more bots: HDV4 (32), James 4 (37), and Kyushu (25).
Don't get your hopes up, No bot beat Etch MKII, but Ebola, Multiply4, Locust, and Occura Amplificis ( ) haven't been beaten by anything else.
