GameMaster needs to be put on, i think it's a fun game. But you might want to make sure the gamemaster can only put one Elite, as the game master can put 3 elites on the top of one uphill ramp and the runners are mowed down without a chance.
Also how about a new idea?
Fight Club: Your only weapons are your fist, you can choose tournament mode or a free-for-all map
Tournament: There are many rings each holding two competetors, once all rings have only one person in them, everyone is teleported so there are 2 ppl in each ring again, this is repeated until only one is standing, if there are an odd number of people, some unlucky people will have 3 ppl in one ring.
Free For All: One giant ring, everyone is place in the ring and fight to the death. Last man standing wins.
