The gunplay is basically the best I've ever played. Its so fuckin' sick. Its Halo but more agile and with more options. I need to upload some videos of myself just wrecking waves of Hive its like a fighting game.. I almost expect a combo meter to appear.
Knife to the face, headshot the guy behind the one you just killed, turn 180 degrees and throw a knife in yet another guys face, double jump up and throw your swarm grenade that pops 4 enemies, bring out dah shotty and mop up the rest, sprint behind a crate and slide into cover, pop your super and sprint out evaporating everything in your path.
You do all of that in like 20 seconds. Its outrageous. I feel present in the combat in a way other, faster shooters don't allow me to feel.
