As Team Fortress 2 and Portal fan games are hit with copyright requests, acclaimed sandbox game dev behind Garry's Mod says the decision is "hardly surprising"

Garry's Mod.

The creator of one of Steam's most iconic games says the company's decision to issue copyright strikes against two fan projects is "hardly surprising."

Garry Newman, creator of physics sandbox Garry's Mod, has taken to Twitter in the wake of Valve's decision to issue DMCA takedown notices against two fanmade games. The first is Team Fortress: Source 2, a project that was allowed to use Valve's Source 2 engine, but not its intellectual property. The second was Portal 64, which Valve asked its creator to take down over apparent concerns about the use of Nintendo technology that isn't in the public domain.
