Update: The Closed Beta has officially wrapped up – thanks to all those who participated.

A few months ago we teamed up with Mechanist Games for the alpha release of its promising browser-based MMORPG City of Steam. The title will officially hit beta status tomorrow, and we’ve got a slew of keys up for grabs that can be redeemed starting now through December 28. Simply post a comment below and we’ll automatically send a key to the email associated with your Exophase.com account within the next few minutes.

Specific dates and instructions on how to redeem are included after the break. The keys provided can be used across all four phases of the beta test.

Chock full of content, City of Steam aims to break new ground in the browser-based gaming space. The game features extensive character and weapon customization, branching storylines, along with 10 races and 4 classes. Additionally, more is on the way, we’re told.

The dev team also plans to incorporate more features based on community involvement — those interested can check out the Steam-o-Meter page for more info.

How to redeem your key:

1. After getting your Beta key, head to the City of Steam website here .
2. Register an account (or sign in if you already have one), copy/paste your Beta Key, click the register/sign-in button, then click on the ‘Play Now’ button and test out City of Steam’s Closed Beta release (or if the test is not yet up, your key will be safely activated and ready for when the game goes live).
3. Enjoy!

The Closed Beta Test will run through 4 periods: Nov. 16-20, Nov. 30-Dec. 4, Dec. 14-18 and Dec. 23-28, starting on Fridays (except for the last test, which runs from Saturday to the following Friday) at 19:00 PST (22:00 EST) and lasting until Tuesdays at 00:00 PST (03:00 EST). Keep your key in a safe place if you’ve received one early. Beta starts soon!
Each Beta season will be chock full of events and activities that will give players a chance to win cool swag and in-game extras. This is still a Closed Beta version, so be sure to help out the developers by reporting bugs on the forum and getting involved with the community. City of Steam strives on community-driven development from input from players like you!

If you would like to support the development further and get some cool extras at the same time, head to the Support Us section of the website.

Note: One account can only activate one single Beta key code.
