Is Half-Life 2 on PSP? No—Source Engine Far Exceeds PSP Hardware Capabilities

No. Half-Life 2 was **never ported to PSP**. The Source Engine's demands (physics, AI, streaming world) far exceeded PSP's 333 MHz MIPS CPU, 32/64 MB RAM, and 166 MHz GPU.

Closest Experiences on PSP

• Half-Life (1998) — NOT on PSP. Only on PS2 (2001, degraded), Dreamcast (cancelled), PC.
• Homebrew Ports: None functional. Source Engine requires x86/ARM64 + modern GPU APIs.
• Similar FPS on PSP: Medal of Honor: Heroes, Call of Duty: Roads to Victory, Killzone: Liberation (top-down), Resistance: Retribution (third-person).

How to Play Half-Life 2 Portable

• Steam Deck / ROG Ally / Legion Go: Native PC performance, verified.
• GeForce NOW / Xbox Cloud: Stream to phone/tablet/TV with controller.
• Remote Play: Steam Link / Moonlight from gaming PC to any device.

Verdict: PSP hardware cannot run Source Engine. Modern handhelds (Deck, Ally) run it beautifully.
