Kaelra
Read full descriptionHide full description
Kaelra is a space strategy game you learn in one minute and never stop learning. The rules fit on a napkin: claim ground, attack where you're stronger. Connected territory is strong. A lone outpost is prey. Beneath that simplicity lies a deep game: - Build your ship - sensors reach farther, engines move faster, but upgrades cost turns while your rival keeps playing. Timing is everything. - Fight for the terrain - volcanoes defend, obsidian strikes harder, and crystals power your engines with extra moves. Every map is different, and always mirrored exactly fair. - Explore under fog of war - a tile's nature stays hidden until your sensors reach it. Kaelra plays under the same fog: no cheating. - One lance, one shield - a once-per-game wall-breaker and a once-per-game bastion. When you commit them is the whole endgame. - Climb the galactic ladder - a real Elo rating from ensign to Kaelra's bane, with an optional online leaderboard of pilots worldwide. Your opponent is Kaelra: an AI that simulates thousands of futures, sees through your encirclements and plays to win. Four levels, from cadet to phantom - the highest defeats seasoned players. No account. No ads. Fully playable offline - the online ladder is optional.
