+**What is BattleCode 2023?**
+BattleCode 2023: Tempest is a turn-based strategy game where you control robots competing to conquer sky islands by placing reality anchors. Win by controlling 75% of all islands through six robot types: Headquarters (build units and craft anchors), Carriers (transport resources and anchors), Launchers (combat), and specialized Amplifiers, Boosters, and Destabilizers.
+
+**How does it work?**
+Carriers gather resources (adamantium, mana, elixir) from wells and deliver them to headquarters. Headquarters use these resources to build robots and craft anchors. Carriers transport anchors to islands and place them to claim territory. The map features time-bending currents that push robots and clouds that obscure vision while slowing movement.
+
+**What's the goal?**
+Conquer 75% of sky islands for instant victory. Islands are captured by placing standard anchors (80 Ad + 80 Mn) or accelerating anchors (300 Ex) that buff nearby allies. Anchors have health that changes based on island occupation. Tiebreakers after 2000 rounds favor teams controlling more islands or holding more total resources.
+
+**What makes it challenging?**
+Success requires managing complex resource chains (upgrading wells, transforming to elixir), coordinating independent robots under bytecode limits, and utilizing terrain effects strategically. Communication is limited to a 64-integer shared array requiring proximity to headquarters, amplifiers, or controlled islands. You must balance resource gathering, anchor production, and military units while navigating time-bending currents and clouds.
