Summer FPS - Lazer Tag and Super Soaker
hapycamper writes "If you want to play your very own 'real life' version of a first-person shooter, two choices include a water fight using Super Soakers or the more technical Lazer Tag brand. GamerDad Unplugged has written up an overview of both systems. In testing, the high end Super Soakers don't seem to be worth the cost unless water capacity is your main requirement. Meanwhile, home Lazer Tag equipment performs well, but can be problematic in indoor settings."
Laser tag seems to have a higher cost of adoption and despite there being a built in scoring system, I've heard that sometimes its not so easy to get a direct hit.
For SuperSoakers, however, you can easily tell when someone has been shot. By the damp and dripping areas of their t-shirts. Unfortunately, there is still difficulty in determining a winner in a team-match.
One idea for a solution is this: after a concluding a team-match a team could strip their t-shirts, hand them to the other team, and wring the loose water into buckets. Whichever team has the least, amount of water wins. And by having the other team wring them out, they have an incentive to wring every last drop. But you would want the other team to watch so that they aren't adding extra water.
Of course if you wanted to make things really complicated you could do SuperSoaker Counterstrike and have a bunch of referees keep track of which body parts get hit and how often, but that's overkill methinks. Oh and if you are as worried about eyes as the Gamerdads are just use sunglasses.
