Is Left 4 Dead 2 on PS4?

No. Left 4 Dead 2 (2009) was released on **Xbox 360, PC (Steam), and Mac**. It has **never been ported to PlayStation 3, 4, or 5**.

Why No PlayStation Version?

Valve developed Source Engine for PC/360; PS3 architecture (Cell) made ports difficult/expensive.
EA published the 360/PC retail versions; no PS3 SKU was commissioned.
Valve has never released a mainline game on PlayStation (except Portal 2 on PS3 via Steamworks partnership).

Platform	Method	Notes
PC (Steam)	Native + Workshop mods	Best version: 4K, 144Hz, 1000s of custom campaigns
Xbox One / Series X\|S	Backward Compatibility	Runs at 4K/60 on Series X; 1080p/60 on One X
Steam Deck	Verified, portable	Native Linux, great controls
Cloud (GeForce Now / Xbox Cloud)	Stream to any device	Requires ownership + sub

Back 4 Blood (2021) — Spiritual successor by Turtle Rock (original L4D devs). Cross-play PS/Xbox/PC.
World War Z: Aftermath — Horde shooter, classes, cross-play.
GTFO — Hardcore co-op horror, 4-player, stealth-focused.
Deep Rock Galactic — Co-op horde, procedural, classes, cross-play.

Bottom Line: L4D2 will likely never come to PlayStation. Play on PC/Xbox/Cloud, or try Back 4 Blood on PS5 for the closest modern equivalent.
