I think my favorite gun is ether the hand cannon (because it feels really strong, hits really hard)or the Sniper rifle( because it DOES hit really hard and has long range) and for ability, Arc Blade. I know we haven't been able to use it yet, but from the videos I've seen it in it looks really good, it has infinite uses when you activate it (it has a time limit though) and each time you get a kill it recharges it slightly, so if there are enough enemy's around you can use it almost indefinitely. So cool.
