G1 Optimus Prime Vs. War Within Optimus Prime
The terrain: A isolated desert encampment once giving host to a small Middle Eastern village.
Objects: A few chickens, goats, palm trees, a small oasis, two motorbikes, small housing development and secret buried human weaponry that would probably come to no use to both Primes.
Rules: As much allowed as any Prime would allow. No holding back on the fisticuffs.
Weather: Scarce sandstorm conditions.
