After confirming that 1 vs 100 will be free. Microsoft have also confirmed that Canada will be receiving a beta version of 1 vs 100 for the Xbox 360 on May the 8th this runs until May the 24th. So rumoured release dates of May the 15th seem unlikely at this point. It is also not clear yet if any other regions will be getting a beta version.
What is interesting in this conformation is that there will be two different versions of 1 vs 100. 1 vs 100 Live and 1 vs 100 Extended Play. 1 vs 100 Live is a two-hour game with a live host in which players may be selected for high-profile roles like the Mob and The One.
1 vs 100 Extended Play is a fast-paced, half-hour show—the more you play, the better your chances of being picked as the Mob or The One in 1 vs 100 Live!
The Beta version will not include skill based prizes that 1 vs 100 Seanson one will have.
The prizes available during the beta will include, an Acer Aspire laptop, a Xbox 360 prize pack, and Xbox LIVE Arcade games.
Also there has been conformation that 1 vs 100 will be releasing in North America and Europe. Not bad prizes for a beta version.
