I am in the progress of creating a fresh spar dropship, one that has more structure to it. Here are the blueprints (Sadly, they aren't blue!).
As you can see I hope to merge the spar dropship and the Alpha map together. Solving the "Too many planets" problem. If you wonder why there are 2 teleports for Alpha, it is so the map is more symetrical :P. So while you play Alpha, and receive a challenge from another player, just warp up back from the map and spar. But, the two rooms are there because each one contains a teleport.
The same queue system will apply. You will wait until you are the next one in, then when you are sent into the teleport room, you stand on the teleport. The teleport will not function unless another spar member is standing on the other teleport. Once a person is on each teleport, they will function and teleport both of them into a room to the theme of a battlefield. Obviously, the size of the room depends on the one you chose.
While fighting down in the spar room you will begin with a countdown timer from 3. You are both immobile until the countdown is finished. Then, once the countdown is done. You fight!
If you die, you simply warp back to the dropship as if you had died on Alpha. If you win, you warp back into the teleportation room and check if there are any more people waiting (Because if you stayed in the sparring room you would be stranded and have to use unstick me :P).
I hope you all agree on this, please if not, state why and I'll try to come to terms.
