Destiny 2 developer Bungie might’ve canceled a livestream meant to show off the gear that’s coming in next week’s Curse of Osiris expansion, but the studio published a brief trailer today to provide a glimpse of the armor, weapons and other new items.

The trailer, which you can see above, contains fewer than 20 seconds of gameplay footage. That may be enough of a tease for Destiny players at this point — after all, Curse of Osiris drops in five days, on Dec. 5. Eagle-eyed fans will notice new weapons like a Veist-manufactured grenade launcher that fires purple robot grenades. This power weapon is known as The Colony, and if its grenades hit the ground, they’ll home in on enemies and blow them up.
