Rust is an open world survival game made and developed by facepunch studios. It is currently in an Alpha stage where you can buy a copy of it for $20 on steam.
The first time the game was played by non-developers was around May or June 2013. Many popular youtubers were given an "Alpha Key" . At this point in time Rust was in Pre Alpha. It was super early in its development at the time.
Personal Experiences(James 2000)Edit
I got the game for $59 in Late september of 2013(Dutch Auction). I played nonstop within the first month i got the game. Then, my iMac broke. I couldnt play any cool PC games until christmas, when i got the laptop i use now.
