Warmind, Destiny 2’s newest expansion, is out now, and while the campaign of the DLC is short, players are finding a lot more things to chase and do than in the previous Curse of Osiris expansion. One of those pursuits is collecting Lost Memory Fragments on the new public space of Mars’ Hellas Basin.

Destiny 2 players have offered their help on the Destiny subreddit, chronicling where each one of those Lost Memory Fragments can be found. Finding them all will result in two major rewards: the Worldline Zero exotic sword and the G-335 Anseris Overdrive exotic sparrow. There are two emblems that will be rewarded along the way as well. The sword is unlocked after finding 35 of the 45 Lost Memory Fragments, while the sparrow is the reward for all 45.

They are spread out across the entire area on Mars that came along with the Warmind DLC. Those who have played Warmind might recognize them as these glowing, projected circles. There’s one that is pretty impossible to miss during one of the first campaign missions of the expansion.

To destroy and claim a Lost Memory Fragment, players must match their elemental damage to the Fragment. Purple Fragments can only be destroyed with a Void weapon, blue with Arc, red with Solar, and the dark red with the new Valkyrie relic weapon. When going on the hunt for these Fragments, be sure to have one energy weapon of each element in order to switch easily between them. Even better, take the Hard Light exotic auto rifle that can now switch elements on the fly by holding down the reload button.

Destiny 2: Warmind is available now on PC, PS4, and Xbox One.
