I'm really enjoying the demo so far though. Deathmatch and Plunder in particular are great with a decent team around you. Elimination is okay, but often rounds end up with someone camping/hiding somewhere. Chain Reaction games seem to be very hit or miss as to whether people know what to do.
[quote name='blader16']Has anybody got past wave 5 or 6 were the gattling gunners come out?[/QUOTE]
I've cleared it on normal once with two really good(read: they were mostly carrying me) players. It gets pretty ridiculous, the higher you go you just cannot run off on your own and just have to try to take the treasure thru the least defended path.
As for those gunners, use grenades, propane tanks, rockets, etc to kill them faster, but often it's more trouble than it's worth unless you cannot get past one of them. I know grenades at least will stun them for a bit allowing you to get some free shots in.
