So, I was bored and wondered if there was a decent mecha MMO and downloaded a few. This was the best one of the few I found. Exteel is a 3rd person shooter much like Gunz except with giant robots. It's free (except for these NCcoins you can use to buy extra stuff) with rather fast gameplay depending on your opponent and yourself. I've been playing it for a day or so now and have enjoyed it. I personally prefer the mode "Last Stand" as its everyone in the game on one team fighting waves of drones. The mecha in the game are able to carry two sets of weapons, the first usually being a pair of guns and the second usually being swords/shield. You can have different weapons to use in these sets such as: SMGs, Shotguns, Rifles, Cannons, Swords, Beam Swords, etc. If you do try this game I recommend going through the tutorial (and when on SMG practice just run, killing those near the checkpoints).
