According to Jerome Weiswasser at UGR Gaming, Bethesda revealed their current progress on Fallout 4 behind closed doors during a 45-minute presentation. Luckily for you, someone was willing to leak some of the information presented. The presentation included a 37-second trailer (video unavailable) as well as some of the following details:
– As it stands now, Fallout 4 will release on Xbox One, PS4, PC, Xbox 360 and PS3. However, this is still subject to change.
– The game is (as of June 2013) 55% complete, consequently, voice actors will be hired towards the end of 2014.
– There is no planned multi-player, but there is a possibility of Co-Op locally.
– The game will take place in Somerville, Cambridge, Arlington (and surrounding areas). The main setting is in a Post-Apocalyptic Boston. However, this area will not be immediately accessible.
The expected launch is in October 2015.
