Seventh Chapter Codex Astartes is for Securing Weapons (Warhammer 40k Boltgun PS5, Mission 9)

Also that is a happy dance at the cactus, because it's an old reference to terrain GW used to make out of common household stuff for Warhammer 40k. Specifically a polystyrene ball and cocktail sticks. These alien cactuses were a regular feature of 40k battle reports in White Dwarf and such. The people who made Boltgun really understand 40k and its history, with little things like this really showing the love that went into this game.
