0legendeveryone 11 years ago I imagine your brother's birthday party has long since passed, but a fun game that I played with my friends was "Braveheart." You use spring pistols or rifles only (since AEGs would be pretty messy) and stand along the opposing sides of a field or yard. Then everyone charges out at the same time firing wildly at the opposing team. It's still a free-for-all, so after the initial charge it's every man for himself. Once you're hit, you fall to the ground (and hope nobody steps on you). There's no cover and no place to reload. It's fast-paced and you can play many times in a short period of time. Another fun game was "Predator," in which one person wears a full mask (we used paintball mask) and hides out in the yard or woods. After a minute or so, everyone else comes out and tries to hunt the predator. The predator is only killed when hit in the head (hence the mask), but everyone else is out with a body shot. Alternatively, you can have everyone else hide and make the predator act like an actual predator. It's pretty fun either way!
