Delta Particles is a single-player modification for Half-Life.

The plot takes place at the universe of HL. You're playing as a technical engineer of complex "Delta Base" Nick Farell. Unfortunately, the protagonist was in the wrong place at the wrong time, as an experiment at the Black Mesa Research Facility resulted in a resonance cascade that teleported extraterrestrial beings from the world of Xen to Earth.

Features:

  • A new single-player campaign consists of 4 chapters (31 gameplay maps + 1 titles)
  • Total conversion, a lot of new content
  • Atmosphere of the new scientific complex "Delta Base"
  • New weapons
  • New Dark Ambient soundtrack
  • BlueShift-style XEN

I’d like to tell you about some significant moments which you probably couldn’t know. Earlier I didn’t expect how many people use Xash3D not so much as a dev platform, so particularly as a game platform. I don’t understand why, but it doesn’t matter.. I decided to add Xash3D support officially after the release of 2021. What does it mean? Mod can’t be crashed on a Xash3D launch, no more “strange black fog” on some of the first maps, fixed broken flashlight (thanks to FreeSlave, who made totally new flashlight instead of hl-engine’s), fixed FOV and other minor changes. Also, I’m very thankful for a1batross’ beta-test on Xash FWGS.

Another significant thing is Linux support. It happened only because of FreeSlave’s great help and support. Server and client so-libraries are already included.

A small graphics improvement: detail textures added.

Wut. Here is the first community-made meme (by orangekid). Was it inspired by FI’s meme? %)

Decided to update the version of 2021. Includes some minor changes.
1) New "TrackerScheme.res" file added which has no crash (as far as I know, it's not actual issue at the moment..)
2) Fixed player's camera FOV: 105 -> 90. Valve added fix for widescreen resolutions with the latest Half-Life update on Steam. Now there's no any sense in bigger FOV.
3) Updated "skill.cfg" file. No "bullet sponge" enemies anymore.
4) Fixed sound noises for player's protection suit voice.
5) Added game icons for Steam.

It's a bit foolish because I had to update it immediately after release.. But why not to do it before the new big update. Also, Here will be a new article tomorrow.

Релиз от 21-го года поддерживает только лицензионную версию игры для винды.
Можно еще попробовать запустить на Xash3D, но придется тогда удалить папку resource/background со всем содержимым, т.к. именно при запуске он может скрашиться.
