The 25th anniversary update for Half-life 1 comes with one very crucial improvement by Valve: proper widescreen support and UI scaling that increases the size of the game menus and HUD to match your higher resolution. This makes the game fully playable on modern 4K monitors with zero inconveniences. Note that this engine update also applies to the Opposing Force and Blue Shift expansions.

A timeless FPS that has been updated for modern hardware. Thank you Valve, now how about an update for HL2 next?
