However, Rust Experimental seems to focus more on the make-shift style by introducing weapons with more rustic looking designs. There were also some make-shift weapons (such as the Revolver, Pipe Shotgun, Hunting Bow, etc), that were generally frowned upon by the community. Rust Legacy featured some interesting weapons based on real life army grade rifles and pistols (such as the M4, MP5A4, 9mm Pistol, Shotgun, etc). Because the game was hosted externally this meant that players could no longer play the game officially after it was removed. Sadly, Rust Legacy did eventually lose popularity and was eventually removed in Devblog 139, 8th December 2016. However, some players preferred the simplicity when it came to graphical options as the settings in the Experimental version can be a little complicated for inexperienced users. Video settings in Legacy were never very in depth since you could only edit "Render quality" (which would edit render distance, quality graphics, etc). Initially, lots of players were satisfied with the choice to continue playing Legacy because the new Rust Experimental would not successfully run on most computers (and some players liked the simplicity behind Rust Legacy). However, by this stage, the game was no longer receiving regular updates as the developers were primarily focused on improving the Experimental version of Rust. However, after creating Rust Experimental in 2014, the developers left the option to go back to Legacy by selecting versions in the steam game menu.
The game was in some aspects outdated which lead to the creation of Rust Experimental (the build we play today). The game was officially released on December 11th, 2013 by Facepunch Studios. Rust (Legacy) is a 2013's (and 2014's) old version of the game Rust built on the Unity 4.5 engine.
