After being in development for some time, Zombie Panic! Source has the huge 3.1 release pushed out which brings with it the official Linux support.
What actually is it? Zombie Panic! Source is a cooperative, survival-horror first-person-shooter. Think of it like a dedicated infection-mode game. Most players start off as humans, while a few Zombies trying to take them down and infect them and have it spread. Two opposing teams, with very different play-styles.
So why did this upgrade take so long? As time went on and they attempted to do a major code rewrite to get around major issues, they realized how "awful" some parts of the game functioned and so they decided to blitz through it all and ship out a much bigger and better upgrade overall. They've said now this is out, they will hopefully go back to more regular updates.
The most major new features are as follows:
- Linux Client support for Ubuntu and SteamOS machines.
- Revamped recoil system to allow players to have more control
- Major source code clean-up and rewrite from the ground up to remove all code from HL2DM.
- New first-person and third-person animations for firearms, explosives and cell phone.
- Improvements to player hitbox registration synchronizing with the player's model animation.
- Reworked the melee system with 'hit rays', creating an arc of line tracers in the player's FOV.
- Enhancements to the Steam Workshop support with additional "Add-ons" menu.
- Implemented Steam Rich Presence.
- 30 new Steam Achievements.
While they only technically support Ubuntu / SteamOS, it does appear to work fine on EndeavorOS, which is pretty much just Arch Linux.
The game continues being free and you can grab Zombie Panic! Source on Steam.
