Thanks Badger, I kept the pickups scarce to keep it challenging even though the enemies are not very difficult. There's a couple minigun ammo, 2 grenade launchers and a lot of enemies drop grenades, a lot of explosive shotgun, ultra health pickup before the final battle. The idea was to make it a challenge even though the battles are introductory level. From there the mapper can build harder levels and add them to the map via the hub system at the initial spawn point.
Hi Rok I didn't know there was a different compile for GoG version, that doesn't sound right. There was a bad model of mine in the beta1 version, try the beta2 and see if that loads up.
Thanks, Gazer
