Headstompers

The Headstompers is a item in Risk of Rain that damages enemies by falling on them.

This item is arguably one of the worst items in Risk of Rain, as it is very hard to deal any damage with it's effect on purpose, and trying is very likely to get the player killed.

Trivia
The text "Recreation of old school video games that you have seen" is most probably a reference to the "Super Mario Bro's" series of games, where enemies are defeated by jumping on top of their head.

It could also be a reference to the MapleStory game item: "Facestompers", as indicated by the "Sent to:" address.
