We have distributed about 90-100 boxes, which should be enough for 12 players actually. However, when it shouldn´t be enough chests for you, we could put some more chests in.
The transformation of the spawn would of course take a little more work to complete. However, the map is really too small for 24 players. Do you even need a small SG map? Because otherwise the cost would be higher than the actual benefit ..
I not ask this out of laziness. We are already working on our 3rd Map and therefore have not much time for extra work xD
