It is similar to another plugin of the same name that is free, but has fewer features, doesn't tell you it is only PVP kills nothing more and doesn't support custom items! If given more love could be a good plugin for PVP and PVE but needs more info in plugin panel of what it is PVP killstreaks kill streaks name is misleading in some ways hope he adds more, or I bought for nothing but no biggie it happens!

Edit: so after talking with dev he has added what i asked for

the plugin can use slight tweaks like custom item name support would be nice and for command support but im happy with it an can now redownload and use for my pve server very nice of dev to respond and add features i requested!
