The Mean Greens - Plastic Warfare, which returned to having official Linux support recently has another big update out and they've dropped the price too.
Patch 1.25 named "Your Dollar's Still Kickin' Butt!" is now out and it comes with quite a few improvements. For Linux gamers specifically, they're hoping this patch will solve some lighting issues on the Toybox Assault map. If it does and Linux gamers confirm it to them, they will roll that same fix out to the other maps.
Outside of the Linux fix: You can now do a backwards combat roll, diagonal sprinting, if you're hit by the flamethrower there's a new effect to show you're on fire and a bunch of new sound effects.
They also improved hit detection, more optimisations to make it perform better, plenty of bug fixes, faster weapon reloading and switching and so on.
Great to see another Unreal Engine game doing well on Linux. For me, it does run very nicely and it is a lot smoother with this latest update.
