You are right about combos and we have them in the fight game play. Your turn in fight is going to be a combination of attack and defense actions. You should control the energy usage and see what part of the body of opponent damaged more. You can also choose when/where to use your super strike and never know when opponent use it too. If you got hit badly you pick the defensive fight method.
Each turn has certain time, because the fight duration is 9 minutes (3 rounds). In short breaks you can recover some health and energy.
Even if you have more health does not mean that you can 100% win.
The 1st test shows that fight is very dynamic, strategic and fun.
