Context: Your spaceship encountered a Grade III Anomaly (now you really wish you'd have read the darn safety manual to figure out what that would be -- too late now). Structural integrity of the singularity containment apparently was compromised, and an all hands abandon ship signal was transmitted by the pilot AI.
Situation: You are now in a place that resembles Ice-Age southern Europe so well, you have a hard time avoiding the conclusion that you time-traveled. Reinforcing this belief is the band of 20 or so Neanderthals currently approaching you.
Moreover, you managed to deactivate and drop your multiband rescue beacon during the late stage night-time parachute descent. Your PA, Vortana, helpfully informed you that given the prevailing wind patterns you experienced, the descent vector after the pod separation event, your flailing arms and general disorientation, the beacon is 95% likely to be in a roughly triangular 100 sq. km. area to the West, and with a smaller 80% probability in a 10 sq. km. sub-area.
You would like to enlist the help of the Neanderthals in:
- Not being killed and eaten (or worse, having to kill them yourself - how horrid)
- Finding food and water (your supplies contain food, but you have no illusions about the quality of spaceliner emergency food rations)
- Finding and re-activating the beacon. To unaided human-like vision, this would appear to be a silver spherical device about the size of a grapefruit. It is virtually indestructible, so the fall would not have even scratched it.
Problem: You recall from your half-remembered education a few centuries back (and Vortana helpfully confirms) that Neanderthals do not speak Common. In fact, it's not clear that they speak at all. How do you communicate?
Supplies: Zero-point powered Gamma-ray gun, a backpack with 20kg of dehydrated supplies, water purifying canister (1), Ssiws Army Knife° (1), rope (40 meters), self-setting tent (1), blanket (1), self-cleaning clothes (2 pairs), Vortana Digital Personal Assistant (1), flotation device (1), rescue beacon (lost), beach towel (1).
° A Ssiws Army Omnitool (aka Knife) can easily dispatch cave bears and moderately large dinosaurs, carve through granite, print circuitboards onto sand. But most people use it for opening beer bottles.
