2703
A large space alien bomb stands upright in the plains, weathered to the point where it is merely the suggestion of a bomb: 1-6, inert; 7-9, still live, disturb it and it will explode (Save vs. Death if within 30' - save equals 2D10 damage, failure is death); 10, actually a space capsule - contains ancient body in space alien battle armor.

A damaged Alien vehicle, with 4 tank treads instead of wheels. Characters with an intelligence of 16 or more may attempt to repair the machine, with a cumulative chance of 10% per week of succeeding. (i.e after ten weeks the tank will be repaired.) It is large enough to comfortably transport 12 men.
A T-Rex corpse, skin mottled red and orange, is being feasted upon by fist-sized maggots. The top of its skull has been removed with surgical precision, and its brain is missing.
