Payload is a cut Zombies mode from Call of Duty: World at War. The objective was to escort an unspecified payload  before the timer ended. Not killing enough zombies would've led to the session ending. A cryptic message at the bottom of payload.str suggests the reward would be to unlock something, possibly as the objective of the payload.
