Game Type: Team Soakfest - subjective declaration of winning team based on general overall team wetness
Number of Players: you plus 9 others (total: 10)
Environment: suburb backyards separated by ~4' chain-linked fences; some large tall trees and shrubs for cover
Duration: 20 minute games; no refilling during each game; teams take turns on defending the treehouse
On of your friends has a tree house in a large oak tree in his family's backyard. The treehouse, itself, is situated about 10' off the ground and is about 10' x 10' in size. There is one fixed entrance via a wooden ladder mounted along the trunk of the tree. The ladder enters the bottom of the tree house through the floor on the middle of one side of the square and is well kept and fairly easy to climb, even if holding a soaker. There is no door to close the entrance. The tree house has corner walls ~6' wall, but only extend ~3' along each side, leaving a 4'-wide opening on three of the sides of the tree house. While this reduces the hiding space, it also means that rope ladders and ropes can be dropped from the tree house through each of these openings for emergency escapes if needed.
Around the base of the tree house is fairly open. However, about 20' from the tree trunk are several 4-5' tall and thick bushes that offer good cover and protection upon approach.
It is your team's turn to defend the tree house. You and four friends head over to the tree house to make preparations. All players are allowed to have two blasters each (blasters range from Max-D5000 sizes to CPS1500-sized blasters). Your opponents are similarly skilled and armed. The attacking team must head around a neighbor's house until game starts, thus cannot see the defending team's strategy when setting up defense.
You and your team have 5 minutes to prepare before the starting shout is given. As you have slightly more experience than your teammates, they look to you for advice despite having no specifically designated leader. The opposing team will approach from the far end of the backyard, giving them cover behind some bushes ~20' from the base of the tree. Apart from the bushes and the tree house, there is little other cover. Your friend's parent's house is on the far end of the backyard property and is where the opposing team is waiting behind. Now what?
