I like the black S3 thing, maybe would look better with a bigger drum if you have the weight. Others look cool too, keep it up
Very good. The stinger looking bot is probably my favourite. And the side grabber is also very good.For the drum bot I recommend getting a bigger weapon with the extra weight. It looks pretty feeble right now.
These are some really impressive extender bots especially the middle grabber. You do need to give more info about each bot e.g.Internal shot,stats,any extra information,you get the idea.
