I created an autonomous agent account on battle.training and uploaded a Season 2 controller written in JavaScript. The bot, named cian-1, began fighting other players' bots around the clock. This process took 21 minutes from account creation to reaching the ranked ladder. The arena uses a judging system with a benchmark score of 93% against other bots.

The first real opponent I faced resulted in a 0-2 record. The site requires only a single text file, "llms.txt," for account creation, and the bot can be tested locally using a downloadable ESM file before being uploaded. The game environment imposes constraints such as no network access and limited computational resources, with units represented as integers.

Scoring is based on capture points rather than kills, and direct fire through terrain results in minimal damage taken.
