We played all 3 scenarios from the book last night. The heroes were Absolute Zero, Bunker and Wraith. Omnitron dominated so much in all three games we felt like we were doing something wrong. It was never close in all three scenarios.
I've checked the rules and the forums here and on BGG and I haven't seen anyone else posting about this scenario. Most scenario discussions seem to revolve around Baron Blade. I was wondering if anyone else has had similar or or different results in this scenario book.
As far as I can see we followed all the rules.
