Airsoft is a game people are playing now. It is sort of like Paint Ball, but they use small rubber bb's. The guns are more realistic too. Some people play capture the flag, others do military style missions, some do re-enactments.
My grandson has an airsoft gun and he had it taken away from him because he shot himself in the eye. It hit the lower lid and left a huge mark. He was really lucky to not have hurt himself even worse.
