You can make things you place on the map respawn faster, like fusion coils. You place one on the map and press X on it and turn the RUN- TIME MINIMUM to the highest.
Now destroy the fusion coil and it will respawn immediately.
If you put a lot, you can make a chain-reaction.
It's fun sometimes, make a room and block it with fusion coils, tell you friend to go in, and then set it off, he will be stuck. Lol
Enjoy!
