Hi, here's my map idea.
A map set in a space station
Idea 1: Activate a lever/button to release gravity and send everyone flying, as in the Blackhole Lab map.
Idea 2: Every 30 seconds, the SAS decompression system opens and sucks all the players out into space, where they die. To survive this, players have to hold on to metal bars, as in the Blackhole Lab map.
