As you explore the various maps that Helldivers 2 will randomly generate for you‚ you will uncover a handful of secrets that can help you not only outside of the mission but also give immediate assistance right there in the mission itself. You can find a drop pod that could possibly have a powerful new weapon for you to use‚ or you could find something that can reveal all the collectibles you might miss on the map. One such surprise is the SEAF Artillery‚ which can be spotted randomly throughout the various missions assigned to you while you play.
