EABA v2 (in development) uses a new system for "combat time". Everyone loves to do "stuff" in a fight, but aside from standing in one spot and shooting (or swinging), getting things done in the normal turn scale of a second or so is really difficult. Hotwiring a car, hacking a computer, defusing a bomb, all kinds of stuff that happens in movies, but which is a bit unrealistic to cram into a ten-second firefight. So, EABA v2 uses an expanding turn scale that accentuates the immediate in the early stages of a fight and the dramatic in the later stages. This lets one player say "I'm shooting at the bad guys", and another say "I run around the building, hotwire a car and then crash it through the back wall". And both of these actions work out on the same time scale, using the same set of rules. It's cool, it's different, I think you will like it.
If you want to see more, head to the forums and look at the EABA v2 playtest section. If the combat chapter is not posted yet, it will be soon.
