Eidos Montreal's Thief reboot, which was recently unveiled in last month's GameInformer magazine, has been confirmed to run on Unreal Engine 3 and not 4 as many expected and will not have any sort of competitive multiplayer.
Speaking with Eurogamer at a recent preview event in Montreal, Eidos Montreal's producer Stephane Roy stated that "Right now, let's say competitive multiplayer, like the example you just gave us - Tomb Raider - there is no plan for that,"
"We are looking to see if there is maybe a challenge mode with some online component, but I'm going to be very honest with you - our main goal with this team is to give you the best single-player experience, just to bring back this franchise, to convince you we're part of the future and not something holding onto the past. It's really demanding, so I don't want to see my team wasting any energy... I want to see them focusing on that."
At the same event, Roy told VideoGamer about the use of Unreal Engine 3 being implemented in the 2014 title. ""Keep in mind when we started, Unreal 4 was [still in] development" continuing that "Light and shadow gameplay is amazingly important on our side so we worked very hard to boost the rendering aspect of the engine, how to deal with the light. So I think it's a question of flexibility. With Unreal it's possible to do it. So yes, it's Unreal 3, but [there are] some modifications."
Thief will be available on Playstation 4, PC and other next generation platforms in 2014.
