The RPGification of Assassin’s Creed might actually be the MMORPGification of Assassin’s Creed, judging by the volume of online-focused challenges, seasonal events, and repeatable content that have been populating Ubisoft’s open-world games. Assassin’s Creed Valhalla has added a new River Raid mode, complete with new cosmetics based on one of the most beloved entries in the series. You have a very short time to get them.

The Jackdaw was your ship in Assassin’s Creed 4: Black Flag, and some callback cosmetics are a natural fit for the new Valhalla mode, which has you sailing to raid location for some good ol’ pillaging. That’s going to stick around for a while, but the Jackdaw cosmetics are not – you’ll only have until February 23 to get them.

The Jackdaw cosmetics are earned in two separate challenge sets. One is a community challenge to play the River Raid mode 1 million times, which has already been completed, netting everyone a hull and sail. The other requires you, individually, to play River Raid. You’ve got to play five times to get the tail, and ten times to get the figurehead.
