Death Stranding Half-Life and Portal Crossover Missions Explained

Death Stranding’s Half-Life and Portal crossover content comes in the form of additional missions delivered to your inbox throughout the game.

Keep checking your inbox and look for messages with Half-Life’s iconic Lambda symbol (λ) in the subject header. For example, the first is by Benjamin H.

Each one wants you to find one of the cubes that accompany Portal in the world. The body of the email will give you instructions on where to find them based on local settlements and landmarks.

Once you’ve found the cube, add it to your cargo pile and return it to a base as you would any other lost cargo, completing the mission and giving you a Valve-themed reward.

There are several that you can find throughout the game, so keep checking your inbox to see if new ones appear as you complete more orders.
