Bring backup gear. Anything that can be nonfunctional, well...
Bring a full set of tools/allen wrenches.
Chrono as early as you can, get your card punched! The line moves pretty well, but it also gets really lenghty, and it sucks being the guy in chrono when the start horn goes off.
Remember once you're on the field, the slugfest firefights aren't the only game going on! There's a lot of field to work with - you don't have to run right up the middle, right up the trail, into 300 guns and get bogged down. Be willing to work up and down the hills to get around the edges.
Like other large scale, large field scenario games, if you have an Apex or Flatline of some sort, this is a really good place to bring it. I was very hesitant to use mine that I'd picked up just to screw around with, but it's been a lifesaver for long range work.
If you've been taken out, BE VISUALLY CLEAR about it! Nobody can hear you meekly say "i'm hit
" over said 300 guns from 150+ feet away, and they'll just keep shooting.
READ THE RULES. As Viper would say, "don't be that guy" that doesn't know the rules, what you can do, and what you can't do.
Heh, the more I think about this, the more things come back to mind.
