After skaters enter the level in Big Head Elimination mode, their heads start to expand. The rate of expansion increases for as long as the round lasts, and the only way to counter the bloat is to do tricks and bust mad flips, as the kids say.
There is one caveat, though. If you hit 100 percent inflation, even while you're in the middle of a massive line, your head will explode. It's a tough balance, knowing when to bank your tricks to prevent your head's steadily expanding affliction and when to keep going. But, hey, if you fail first, you can spend the rest of the match tormenting others as a headless skater.
Time Attack is a bit more self-explanatory, dropping skaters into locales and tasking them with amassing the most points to win the round before the timer runs out. On the smaller levels this is a more harrowing prospect, as skaters can run into each other and kill each other's lines with relative ease.
Rounding out the rest of the multiplayer suite in Tony Hawk's Pro Skater HD is Free Skate, a less hectic multiplayer mode where everyone just chills out and skates around a single map like best buds – at least, that's how we imagine it'd be if gravity didn't totally conquer our social circle so many moons ago.
Tony Hawk's Pro Skater HD launches on Xbox Live Arcade on July 18 for 1200 MS Points ($15).
