Fun with a nice Cannon Fodder vibe, but a bit too buggy. Sound just gives up after 5 minutes or so and sometimes my teammates seem to become indestructible - after I reset so I could NOT buy certain upgrades, I beat normal mode at level 3 easily thanks to that...
@diviad: 5PG's games are littered with subtle pop culture references - if you don't get the significance of Ludicrous Speed/Plaid then you need to watch Spaceballs ;) Also, that happened to be the final megabrawl for pretty much the reasons you stated - the devs have already committed to reworking the format into something less grindy. Have to agree about programming, though - at least it doesn't leak memory quite as horrendously as Dawn...
