and the bf2142.com site has been asking when and if a demo version will be released….
BF2142.com- We noticed that you have confirmed the release of a demo at a later stage, could you give us more information about it, as in how far before or after the game release the demo would be out?
DICE- The demo for BF2 went out about 10 days before launch if I remember correctly, I am sure something similar will be the deal for 2142. We are also going to throw out an open beta in the beginning of August. The beta is predominately to learn about large scale issues, i.e. when we have 10 000’s of people playing at the same time, eliminating some of the problems we have encountered after launch previously in the franchise. Keep your eyes open to join.
They also have some new screenies and renders to take a peek at..
