Red Comrades Save the Galaxy: Reloaded is a remaster of a 1998 point & click adventure game that was rebuilt for Unity and it is now available on Linux & SteamOS too.
Nice to see another classic game get revamped and get a Linux release. Never heard of it myself, but reviews on Steam indicate it's being well received.
About the game (Official)
Russia is in a midst of Civil War. Both the front line and Ural River splits the village Backwoods in two. One part of the village is somehow controlled by the brave Red Army division headed by Chapaev. Remnants of the cowardly Whites are still comfortably stationed on the other side.
Vasily Ivanovich Chapaev and his fellow aide Petka wake up to find themselves in a bad hangover and in a worse mood. They realize that someone has stolen the Red banner from the HQ. Our heroes are totally depressed with such a misfortune, just like every decent Red army fighters should be.
This unbearable offense leaves them no choice but to sneak into the enemy territory and to retrieve the precious banner.
Although it's not the end of the story yet! Somewhere on the moon, legions of alien invaders prepare to conquer Earth. But could such a little thing really give a scare to the Red Army heroes?
Thanks for pointing it out Vadim.
