If you're hoping to try out Rainbow Six: Siege ahead of release without committing to a preorder, you're in luck.

Right now, Curse is offering access codes for the upcoming Siege beta. The only requirement is that you have a Curse account, which you can get for free at its website.

Once you have an account, you can grab a code at Curse's giveaway page. You'll then redeem this on the official Rainbow Six website, where you can choose which of the game's three platforms--PC, PlayStation 4, and Xbox One--you want to play on. There's no telling how many codes there are to go around, so if you want one, you should act fast.

The beta isn't set to begin until September 24. Initially, the only way to guarantee yourself access was to preorder, though Ubisoft also has a waiting list you can sign up for on its website in the hopes of getting a key.

Alternatively, as noted in the video above, Ubisoft has partnered with Extra Life, and by donating $6 or more to the charity, you can get yourself a key.

Siege is set for launch on October 13. An alpha was run earlier this year, but unlike that PC-only test, the beta will include both PvP and the returning Terrorist Hunt mode.
