Kinglink says “So we begin the Humble Monthly Bundle Reviews for December 2018 with Metal Gear Solid 5: Ground Zeroes, which is a mouthful, so Ill probably just call it Ground Zeroes for brevitys sake. Its a game from 2014 that was to introduce people to the new Metal Gear Solid 5 system and the brand new Fox Engine. Now it can be found bundled along with Metal Gear Solid 5: Phantom Pain definitive edition. Lets talk about just the Metal Gear Solid 5: Ground Zeroes game.”
