A Machine for Pigs. Soma was self-released by Frictional on 22 September 2015 to generally favourable reviews and initial sales higher than those of Amnesia: The Dark Descent within the first days: Soma sold 92,000 units within ten days (in contrast to the 20,000 first-week sales of Amnesia: The Dark Descent), and 450,000 units in its first year (in contrast to the 390,000 first-year sales of Amnesia: The Dark Descent). In 2016, Frictional Games announced that it began the production of two new, yet unannounced games, as a result of the high profitability of Soma. By 2019, it also planned to start pre-production on a third unannounced game. In August 2017, Frictional moved from Helsingborg to new offices on Stora Nygatan in Malmö. Around this time, the company had 16 employees. The Malmö offices housed half of its 25 staff members. Amnesia: Rebirth, a follow-up to The Dark Descent, was announced with a trailer in March 2020 and was released in October 2020. HPL Engine The HPL Engine is Frictional's in-house game engine.
