nightcraw1er.488: Serious Sam?
OP: Not that I can think of. FPS now seem to all be in the vein of linear walk through sparkly graphics stopping for the occasional cutscene or set piece event, know as the COD effect. Painkiller is not bad, though not sprawling by any means, same with the newer shadow warrior.
Strijkbout: I agree that the shooters I mentioned are linear but they don't feel like it, because like the OP mentioned of the leveldesign.
Serious Sam and Painkiller are completely different style shooters and can be compared better with arcade games like Robotron 2084 or SmashTV while the singleplayer of Call of Duty is more of a shooting gallery, the levels are too simplistic for even a linear experience.
Sorry, that OP:... was to the original post, not to yours :o)
Fenixp: STALKER: Shadow of Chernobyl, STALKER: Clear Sky, STALKER: Call of Pripyat, Far Cry, Far Cry 2, Far Cry 3, Far Cry 4, Far Cry: Blood Dragon, Crysis, Crysis 2 to an extent, Crysis 3, Bioshock, Bioshock 2 (not Infinite tho), Chronicles of Riddick, Dishonored(I suppose), Deus Ex: Human Revolution(I suppose), ArmA: Cold War Crisis, ArmA 2, ArmA 3, Borderlands (kinda bad otherwise tho) and the list goes ON
I stand corrected. You are quite correct, STALKER, Far Cry 1, Crysis 1, are all great games and pretty open. I would point out that Bioshock was not open at all, ok in one of two places you could go left round the pillar or right, but that is it.
