2. 2Pick off fast, small enemies first. They reach you quickest and are easiest to lose track of.
3. 3Reposition between waves if the game allows movement; standing in the same spot makes you predictable.

Active Defense is a free browser shooter with no install and no account. It gets to the point within seconds. Rounds are brief and intense, and the score at the end is a clear, honest measure of your reflexes that day, which is reason enough to come back.

Suits players who like fast, target-driven play, mainly teens and adults. Older children with good coordination will manage the early waves. It is not aimed at very young players.

Is Active Defense free?

Yes. All games on this site are free to play in the browser. Press Play and it opens in a full-screen player with no download.

Why can I not fire continuously?

Many shooters limit fire with ammo, cooldowns or heat. It is a design choice that rewards accuracy. Fire in bursts and reload in the gaps.

Does it need a powerful computer?

No. Browser shooters are light and run on most laptops, tablets and phones from the last several years. A current browser matters most.
