Biodome Drops

On Moon, you don't really want to trade in when you run out of ammo because you can go to the biodome and get drops if your 3 Gersches do not give any drops. If you trade out too much, you will get frame lag. Also, since you have to trade out your Gersches for QEDs and then get Gersches back, and also trade out the Wave Gun, it is usually faster to just get a biodome drop.

It takes 1-3 minutes for a new power up to spawn in the biodome, so don't use the pads until at least a minute has gone by. The reason for this is because the pads have been to known to cause reset/g_spawn faster if you use them too much, and also you can make sure you use the right pad if you are on the ground when it spawns.
