Risky game, half-finished game; half the price, half the risk
Rust is an odd game, a cruel mistress, a wild card and in development for a long time, with no clear end or goal in sight. Its part survival, part crafting and part meditation on the human condition - via anonymous Internet dickery. It also happens to be hilarious.
"Rust’s world is harsh. The environment is not kind. Bears and wolves will chase and kill you. Falling from a height will kill you. Being exposed to radiation for an extended period will kill you. Starving will kill you. Being cold will kill you. Other players can find you, kill you, and take your stuff. Fortunately for you, you can kill others and take their stuff. Or maybe you can make friends and help each other survive, using the game’s building tools to create a safe haven. We provide the tools. How players survive is up to them", is how the developers describe their game on the game web-site.
Facepunch Studios are updating it on a weekly basis, and if you are confused and unsure weather its worth your hard-earned cash, now might be a good time to give it a shot, since its 50% off on Steam.
