Warpath 2.0 is definitely a wonderful set of rules. The key difference this time around is that 2.0 is built upon extensive public beta-testing, which a lot of us took part in.
The alternate activation system is one of the few that works extremely cleanly and smoothly, and it incorporates morale (suppression and inspiring from leaders).
So, you can have a situation in a game where before a unit gets to activate, you shoot at it and suppress it (making it harder for the enemy to activate), but then your opponent reacts to this by moving their commander over to the unit to give them a re-roll on their activation check.
It creates a very interesting "shooting-focused" game that isn't just about gunlines, but favours mobile firepower and action/reaction.
Highly recommended! Warpath Kickstarter is coming in a few months time, make sure you keep a look out for it.
