To answer your question, all the powerups in KA will work as instant powerups (you touch it and it activates automatically), due to the gameplay's speed, the included powerups in the latest version of KA are the dark servant, which teleports near battles to finish with your enemies <!-- s:twisted: --><img src="{SMILIES_PATH}/icon_twisted.gif" alt=":twisted:" title="Twisted Evil" /><!-- s:twisted: --> , the shadowsphere from heretic, the icon of the defender, which makes you invinsible for some time, and some new items that are yet to come <!-- s;) --><img src="{SMILIES_PATH}/icon_wink.gif" alt=";)" title="Wink" /><!-- s;) -->. As for balance, don't get a wrong idea, the latest beta released was lacking some balance measures that we have made, now all the classes are WAY MORE balanced than before, and the bots will work WAY better too <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->.
