First it was, then it wasn’t, now it is. Ubisoft has confirmed that is going to come to PC, but that it will be after the console releases. The official release date is currently “at later date” than the console editions.
It was previously announced that the free-to-play Ghost Recon Online would be released instead of Future Soldier, but that is not the case – both games will be coming to a mouse and keyboard near you (perhaps even one on your lap).
In other news, Future Soldier 360/PS3 has – but there will be a multiplayer beta on both platforms to make up for that in April.
