Call of Pripyat: Redux is the premiere realism/difficulty modification for the latest game in the S.T.A.L.K.E.R. series. Version 1.0 (released) brings numerous enhancements and tweaks to the game while retaining its original charm, but making the Zone a much more difficult place to survive. Version 2.0 (in development) will build upon the success of v1.0 and bring a huge range of improvements over its predecessor, including new missions, NPCs, script systems and even levels.
You can't always make it back to camp before night's veil descends, but a fire should keep the mutants at bay long enough to last until morning. Nap with one eye open, and always keep someone you trust awake and on guard.
