Version 1.4 of the Spirit of Half-Life has been released:

Spirit of Half-Life version 1.4 is out!

This time around the release is a community effort, headed by ytiAdmin and Confused. Respect to these guys.

Feature highlights: An ambient_fmodstream entity, capable of playing .mp3, .wma and .ogg files.

env_particles can now be multiply instanced - for all you people who like to make streams of water/goo/blood/fire spurting out of bullet holes.

weapons and ammo can now have a 'master' to stop them being picked up (perfect for tempting people from behind thin-walled gun cabinets),

trigger_onsight can now look from multiple entities of the same name, and no longer looks from dead monsters (you could have 3 patrolling grunts, and activate something whenever one of them sees you),

The model mirror entity... which does exactly what it says on the tin.

Not to mention loads of new demo levels and documentation. And that's just the tip of the iceberg!
