The future of Nottingham-based studio Crytek UK and Homefront The Revolution appear to be under serious threat.
Recent reports claim that a significant portion of Crytek UK staff have stopped working after having not been paid in full for multiple months. Former studio development manager Ben Harris also resigned last month.
According to previous reports, Crytek UK employees are said to have only received around a third of their wages following the alleged cancellation of Ryse 2 in March. Others claim to have not been paid at all "in months".
Crytek has remained more or less silent on the exact nature of the situation since late June, when it denied claims that it is on the verge of bankruptcy.
Open-world FPS sequel Homefront The Revolution sees players leading a resistance movement in guerrilla warfare. It takes place in Philadelphia, four years into a brutal military occupation of North America.
