Chaos Caves

Chaos Caves is an all-action couch game where you blast each other with completely unreasonable weaponry. Games last about a minute, everyone gets a turn at the Nuke, and failure is just as funny as winning. Next time, grapple out of range!

Region: Global. Check that the key's region matches your Steam account's country before buying — region-locked keys can't be activated elsewhere.

What you get: one unique, unused product key, shown on your order page (and in your account) once payment is confirmed — usually within minutes, and at most 24 hours. No physical item is shipped.

How to activate: open the Steam client, choose Games → Activate a Product on Steam, accept the subscriber agreement and paste your key. The game then appears in your library, ready to download.

Requirements: a Steam account and the Steam client. System requirements are set by the publisher and listed on the game's Steam store page.
