Co-op, third-person shooter Warframe is hosting a free open beta weekend from Friday, February 15, 12:00pm EST to Tuesday, February 19, 9:00am EST.
No beta key is required to join; those wishing to take part should simply register at Warframe's official site.
To celebrate the open beta, developer Digital Extremes has designed an exclusive weapon available for this weekend only, which will be in the market for just one credit. The Braton Vandal is a limited edition rifle that has a lower fire rate than the standard model, but higher damage per shot.
Warframe is scheduled to be released as a free-to-play PC title.
