Hinkka has ported Quake I engine to the S60 3rd Edition platform. The port is fully functional and works very fast, the only missing thing is network play. The software works only on S60 3rd Edition FP1 (Feature Pack 1) phones (e.g. the N95, E90, 6110, etc.) equipped with ARMv6 processors. The port is Open Source and uses Symbian's P.I.P.S libraries. I must say that Quake looks really impressive on E90 Communicator's huge internal screen.
