Gene of Haven† has charged our intrepid heros with traveling to the ancient cybernetic installation called Mindkeep and query the memory core there for the answer to these riddles:
“Where are the Cities of Man?”
“How can people reach the Cities of Man?”

An encounter with the half-man hermit Ermon on the Blue Food Flats only deepened the enigma.

This is essentially a Gamma World campaign set in the world of Killraven using GURPS 4e mechanics.  It is cinematic soft Science Fiction after the apocalyptic Martian invasion and conquest of the Earth.

Changes from Killraven cannon:
The invasion takes place in 2038.  It is now 2138.  In addition to using our nuclear stockpiles and biological weapon against us, the Martians have also done something to ruin gunpowder-based ammunition.

Changes from GammaWorld cannon:
The holocaust was caused by the Martians (duh) and it has just been 100 (not a 1000 or more) years since.

New players are welcome: 150 points (total) with up to 40 in disadvantages (plus up to 5 more points in quirks), cinematic or alien skills and advantages are encouraged!  It is absolutely fine if you are new to GURPS as this campaign should be a good introduction; just message me your character concept and we will work it out over email.

Gladiators are the archetype, but there is room for a Keeper (mad scientist) and Freemen of all stripes survive.

Do not count on guns or vehicles to begin with, but other relics are possible.  Equipment should be based on your character concept, but $5000 (TL5 suggested starting wealth) is probably about the right amount.  Poverty and/wealth disadvantages/advantages are discouraged.  I tend to be a rules light GM, but that’s partly because GURPS gives me that flexibility.

Follows are some more helpful links:

• An open source Java based fully interactive Gurps 4e Character Sheet (GCS) (GCS) generator.
• Blank PDF character sheet.
• Online Javascript-based GURPS 4th edition Character Generator which is very easy to use, but may be too simple for mutants and cinematic skills.
• List of Killraven Characters from the Appendix to the Handbook of the Marvel Universe.

† Honest, it’s right out of the 1986 module that I am using!
