Quake III Arena is the latest game to see AI top humans

Google's AI subsidiary Deep Mind has built its reputation building systems that learn to play games by playing each other, starting with little more than the rules and what constitutes a win. That Darwinian approach of improvement through competition has allowed Deep Mind to tackle complex games like chess and Go, where there are vast numbers of potential moves to consider.
But at least for tabletop games like those, the potential moves are discrete and don't require real-time decision-making. It wasn't unreasonable to question whether the same approach would work for completely different classes of games. Such questions, however, seem to be answered by a report in today's issue of Science, where Deep Mind reveals the development of an AI system that has taught itself to play Quake III Arena and can consistently beat human opponents in capture-the-flag games.
Not a lot of rules
Chess' complexity is built from an apparently simple set of rules: an 8x8 grid of squares and pieces that can only move in very specific ways. Quake III Arena, to an extent, gets rid of the grid. In capture-the-flag mode, both sides start in a spawn area and have a flag to defend. You score points by capturing the opponent's flag. You can also gain tactical advantage by 'tagging' (read 'shooting') your opponents, which, after a delay, sends them back to their spawn.
