Aside from Portal: Companion Collection (and its hidden Half-Life 2 chunks), yesterday’s Nintendo Direct Mini also gave way to other announcements like Persona on Switch.
After yesterday’s Nintendo Direct Mini, Valve released Portal: Companion Collection, a bundle of Portal and Portal 2 for the Nintendo Switch.
In fact, there are so many pieces that they were able to fully mod Half-Life 2 onto Switch using the fragments hidden within Portal.
@OatmealDome pointed out that Portal having bits and pieces of Half-Life 2 is expected because “Portal 1 is just a fancy mod of Half-Life 2.”
