Valve are releasing Alien Swarm later for free – with the full source code as a bonus. This is an updated version of the old Unreal Tournament mod.
Alien Swarm has been recoded into the famous Source Engine and is set to look rather attractive if the videos are anything to go by. It will include Steam support, such as cloud storage, Steamworks Tools and full community aftercare.
Valve hired the team behind the original UT mod, Black Cat back in 2008 and they have worked on Left 4 Dead 2 and Portal but in parallel, they were working on Alien Swarm as well.
“If you’ve ever thought about developing a mod on the Source engine with Steamworks, this release provides more insight and examples for using Steamworks in game production,” said Valve.
