Attack

Attacking is a different discipline from defending, and these games know it - you're the one making the first move, and there's no waiting to see what happens.

Combat Guardian: Under Attack is the one that plays both sides, so you're switching between pressing and holding. Attack Hole takes the idea somewhere strange and satisfying, consuming everything in your path rather than shooting it. Tank Challenge puts armour behind the advance, and War Nations.io replaces the computer with other people, which changes how bold you can afford to be. You're deciding when to commit rather than how fast you can click, and that's a more interesting question.

There are 9 free games under this tag, all playable in the browser with nothing to install, and they're mostly about committing at the right moment rather than clicking quickly.

The tactical side belongs with Strategy games, and Combat Games is the tag for anything built around a fight.
