Another small ONS map, but this one is made for masochists... or the very brave ones
The map is also a small but open space, lots of vehicles, lots of guns, nukes and ION painters, what's the catch? Use them without killing yourself or your teammates.
For invasion with the monsters used on DM maps (titans and queens) this one will be challenging, but if you want to make players sweat ink replace queens and titans with warlords.
