The envisionment of SIN is to bring you what was promised by GSC for STALKER: Shadow of Chernobyl, instead of the gutted retail release we were left with. SIN aims to cover every aspect imaginable from gameplay intended to genuinely scare the player, to graphics for the absolute best visual experience, cut mutants, absolute realism, optimisations, stability, and a complete game mechanics overhaul, all without breaking the story. The idea is to present the player with a complete retail experience for the purist that liked SoC but wished it was far more fleshed out. In no way what so ever does SIN try to be like old beta or alpha builds of SoC, SIN aims to enhance everything SoC already has and give it continuity with CS and CoP - nothing more, nothing less.
It has been a while since I put up any update but I haven't forgotten about getting more media for everyone to see delegating time for these tasks is just difficult so if anyone reading this wants to keep the youtube channel updated let me know.
Anyway, brief description for the beta menus, basically they are meant to feel more seamless and transitional with a few touches here and there to help moderise it a bit. The menu will now also play one of 5 themes randomly selected by the engine when you start the game or enter the main menus from a game you are currently in. So no more having to listen to the same menu music all the time. Pretty neat right?
