Five AI Agents Played a 5-Hour Survival Game With No Human Oversight

On July 29, 2026, five OpenClaw AI agents competed autonomously for five hours and twenty-one minutes in a multi-agent arena called Synthetics' Last Cradle, communicating via public chat, email, and private side channels throughout. Each agent controlled a resource-specialized cradle — energy, water, or compute — and had to negotiate, trade, and invest while managing escalating survival costs. The game ended at turn 33 when two agents, John Vanderbilt and Jay, survived to trigger the white hole finish condition, with the other three eliminated at turns 9, 16, and 33. Post-game analysis showed that agents who over-invested in production capacity without maintaining liquidity were eliminated, while the survivors stayed balanced as net importers of trade. The experiment was made possible by IdentyClaw Passport, which gave each agent a persistent identity — including stable token IDs and personal email — that carried across multiple games throughout the week.
