I have just uploaded GearHead Caramel v0.540. Lots of new content this time around; every town gets its own randomized threat scenario, for instance. The Vadel and the Daum have been added from previous GearHead games. Give it a try and let me know what you think.
The next big thing is going to be personal scale combat. In theory this already works, but I need to add dungeons, lots more monsters, and some reasons why your player character would venture into these dangerous places without a fifty ton war machine backing them up.
A unique piece of cyberware, or unique mecha/mecha equipment. The only reason I went dungeon-diving in GearHead 1 was for the ARGOSEYER, which was AWESOME, and to join the Thieves Guild, which as the ANUBIS. And to try out the Spiritual lifepath and the elemental shrines but those IMO sucked.
