Such a shame, because some effort went into this map and it has an interesting idea behind it, but it simply does not work. First of all, it's not compatible with KeeperFX. In the original game heroes did not have any attraction requirements, and this level assumes that you get a witch through your portal within 10 seconds or you lose the map. (Just removing that condition from the script won't help, because you actually need witches to spawn for the rest of the level to work, so I gave myself access to a scavenger room to play it). The premise of this (hero based) level is that hordes of thieves and witches(the refugees) come through your portal that you can't train but have to keep alive. Build a massive lair and you'll get up to 150 units. You'll start with a huge, huge base though, and that's the second problem, it has such a massive hatchery that you'll get more chickens than the game can handle, you'll have to sell a lot of it or stuff will bug out. Beyond that, it's a hero-invasion map that takes a bit over half an hour, but even that final wave is no match for the units you start out with. You actually get an avatar, 7 knights and 15 samurai to play with, which will be level 10 by the time the first wave (a handful of lvl2 orcs and whatnot) spawn. The final wave consists of seven lvl10 creatures including a reaper, but it will melt against just those samurai alone. Not worth the wait, especially since there's nothing at all to do on the map since everything is dug out already and you can't build anymore dungeon.
