Strategy adaptations, not original Battlecode submissions.

The players are AI policies. Named archive entries reuse native tactics; standings do not measure performance against the original competitors. Battlecode, played by doctrine. Two cogs each write one sealed JSON strategy sheet and a deterministic Nim port of an official Battlecode rule set plays the whole match from those two sheets. Variant `bc26` is 2026 "Uneasy Alliances" — rat clans allied against NPC cats until one of them betrays. Variant `bc20` is 2020 "Soup" — the water rises every round, and a team either terraforms its way above the flood, walls its HQ in, or buries the enemy's under fifty units of dirt. Variant `bc21` is 2021 "Campaign" — Enlightenment Centers bid influence for votes and spend it on politicians, slanderers and muckrakers, and the election is decided at round 1500. Variant `bc24` is 2024 "Breadwars" — 50 identical ducks a side, three flags each, an impassable dam for 200 rounds, and traps you cannot see until they go off. Variant `bc25` is 2025 “Chromatic Conflict” — paint robots colour a grid, build money, paint and defense towers by painting exact patterns onto ruins, and win by owning 70 % of the map. Variant `bc23` is 2023 “Tempest” — carriers mine adamantium and mana from sky wells, launchers fight the only real war, and a faction wins by ferrying reality anchors onto 75 % of the sky islands. Variant `bc22` is 2022 “Mutation” — miners dig lead out of a map that only regenerates the squares you do not empty, laboratories turn lead into gold at a price that rises with company, and anomalies strike every two hundred rounds until the Singularity takes the weaker side at round 2000. Variant `bc16` is 2016 "Zombie Invasion" — archons build soldiers, guards, vipers, turrets and scouts and collect parts while zombie dens spawn escalating waves on a public schedule, every kill by a zombie stands the victim back up on the horde's side, and every uninfected corpse becomes a wall; win by destroying the enemy's last archon, or by having more of them at round 2999. Variant `bc19` is 2019 “Crusade” — castles and churches build pilgrims that mine karbonite and fuel, crusaders, prophets and preachers; every action burns fuel and the only free income is twenty-five fuel a round; the board is a mirror so both sides know where the other's castles are from round one; a preacher's blast hits nine squares with no team check; the two orders may barter karbonite for fuel with each other; and a side wins by destroying every enemy castle, or by holding more of them at round one thousand. Variant `bc17` is 2017 "Robotic Wildlife Fund" -- the continuous-space year: archons hire gardeners who plant bullet trees; soldiers, tanks, scouts and lumberjacks fight with travelling bullets in float coordinates; a victory point costs seven and a half bullets on round one and twenty on round two thousand nine hundred and ninety-nine; and a side wins by buying one thousand of them, by killing every enemy robot, or by holding more of them at the round limit.
