Old RuneScape was a browser game built with the Java programming language. RuneScape has two combat mechanics: Legacy or Regular (commonly referred to as EoC, or Evolution of Combat). New version of Runescape is available to download and install from source.

The Regular (EoC) fighting style gives players a plethora of abilities to utilize depending on the various weapons, items, and armors they have at their disposal.
Legacy mode is the original combat system the core game was originally designed around. There are no abilities, Adrenaline, or any of the combat settings in EoC. Your character attacks automatically, although you can use items and Special Attacks.
There are currently five types of skills available to players in RuneScape. Each skill type follows the same basic principles of training in their respective type.
Before starting the tutorial, players must create a new character. They are able to customise their hairstyle, beard and clothing.
While playing, you think of nothing but the game. An interface at the top left of the screen indicates what stage of the tutorial the player is on, and their total progress through it.

RuneScape can be played free, but also offers optional membership that unlocks even more thrilling content, including 8 additional skills.
A sequel to the game was released in 2004, and that’s when Jagex made the decision to rename RuneScape into RuneScape Classic.

Despite the active player base, Jagex hasn’t supported Classic for years. The developer touched on that in its new blog post, claiming that safety tools have become a serious issue.
The number of bugs is getting worse, and we’re gradually seeing the game breaking. It’s important to highlight that these are bugs which we can’t fix due to the unsupported nature of the game.
