VScript

VScript, introduced since Left 4 Dead 2 and later backported to Team Fortress 2 (and other games on its branch), is a virtual machine for scripting that acts as an abstract binding layer between the Source and Source 2 engine and external scripts. According to the Alien Swarm - SDK, the following scripting languages are supported or could be in the near future:

• Squirrel
