I've been looking through the UK Released thread, and I found a lot of complaints. I think we should post them here, just so we don't go off topic. Here's mine:
The RefBot just shoves you aside, when he should move around you and isn't the way he should be.

The House Robots come out whenever they bloody well like, and don't always stay in the CPZ, even if they have a red card.

The Flywheel weapons aren't fast enough.

The Pincer weapons should do damage.

You should be able to design your own weapons and chassis. That's what I expected from a PC game. Well, the chassis part anyway.

If you play as the House Robots (using cheats thanks to thepimp), you can see behind Killalot at all. You can't see if his pincers are working, and his lance just goes up and down. WTF's up with that?!

When playing Football in Arcade Mode, the opponent doesn't go for the ball-he goes for you instead! Also, I think Dead Metal should be the goalie, not Killalot. He's too damn big!

When using Dead Metal yourself, you can't see if his pincers have grabbed an opponent, and his saw doesn't move forward!

There are more, those are the only ones that I can think of. Post your complaints here!
