hook mod and jetpack mod are fun but maybe they are getting old
how about a new mod that charges players' powers and give them ability to do something special?
like sprint aux, whenever players damage other players, they will get energy and once they have enough energy charged, they will have a choice to eithier release a very powerful attack or increase their health and armor or whatever. Just a thought
It's gonna be like a mini class system but not as boring as TFC style class system...
