Can you put more then one monster spawner in a level?

Or whatever you call it. Its the thing from level 30 that shoots monsters.

Yes.

Thank you.

Be careful how many you put down, though. IMO anything more than 3 will cause big problems depending on the map. (but you can make them appear on certain skill levels like any other thing)

You should be fine as long as you don't have more Shooters than Spawn Spots, otherwise the monsters will end up inside each other. HR2 MAP30 had eight and there weren't any problems.

BTW, on Skills 1 & 2, only one Boss Shooter will appear(the one with the lowest item number).

Another thing to keep in mind are the arrangement of the Spawn Spots. The Shooters dispatch the cubes to each individual spot in a cycle based on the item numbers of the Spots(lowest to highest).
