I don't friggin' know how to play Peekaboo...

Peekaboo is a difficult map to play on because you and your opponent are attacking via separate paths, unlike Glitch, where most units funnel through the center (except the ones sneaking around), and Sharkfood, where both of you want to take the top, so it's tough to build an offensive force while maintaining enough units at home to make sure you don't get swarmed, yourself.

So yes, the most common strategy, especially for Scallywags, is to hunker down, build Bombshells and Soldiers, trade some Runners here and there, all the while trying to build up a large enough Wit reserve to charge forward and cause irrecoverable damage in one mighty swoop.

Some players like to take the offensive early on, assaulting the opponent's Wit Space quickly before such a force is assembled, but in my experience, unless you've got Mobi on your side, these early offensives quickly equalize, leaving both players to go back to building stuff for another few turns. This whole map is silly.
