AlternativA

AlternativA is an unconventional and ambitious project with great ideas, but debatable execution.
You play a civilian drawn into the Zone under the influence of an unknown and mysterious entity that keeps haunting your dreams.
With four playable factions, dozens of locations, heavy use of cutscenes, mysticism, horror elements, seasonal changes and brand new, unique mechanics rarely seen in the S.T.A.L.K.E.R. universe, the sheer scope of the mod is impressive. Each faction's storyline eventually reveals different fragments of the same overarching narrative, and the full picture only emerges after multiple playthroughs.
These ambitions come unfortunately at the cost of stability, bugs, balance issues, and very often prioritizing atmosphere over clarity. If you're an experienced and patient player, willing to tolerate jank, plenty of trial-and-error, frustrating moments and a lot of backtracking, it will offer one of the most unusual and memorable experiences in S.T.A.L.K.E.R. modding.
