This fine looking chap is a 500 GB external hard drive. It’s modelled on the title challenge in Shadow of the Colossus. Shadow of the Colossus is a action-adventure game for the PS2 back in 2005/2006 when they was moved over to the PS3 for 2011.
The game had you track down and fight many different colossi. Typically they only had one weak spot.
This superb mod was put together by redditor Foxfoxwaltz, shared and loved by the community. Foxfox has skills. In addition to the Colossus he’s also posted the building steps for a Last Guardian speaker enclosure which looks even more complex!
