This is by far one of the best tactical combat systems I've ever played. It's got mechs fighting it out on futuristic battlefields.
The rules are simple but rewarding, and the fights are quick and satisfying.
If you want a quick, simple game that will pass time while someone goes to get snacks, but still leave you wanting to play again the next session, you can't beat this in terms of free products.
There's really not more to say.
