NakedAVP has been released in version 1.3.1.

NakedAVP is a modern port of Aliens vs. Predator Gold (2000) by Rebellion Developments, based on the icculus port for Linux, macOS and Windows.

The update is mostly fine-tuning over 1.3.0: mouse fixes and rendering optimizations (by Sol1vaN), fixes for crashes and display bugs when changing resolution, GLSL shaders (adapted from Frictional’s HPL1 engine), dynamic lighting for muzzle flashes and particles, and bloom/lite-HDR effects.

Another monumental release! Mostly a huge amount of tuning from 1.3.0
