Crimson Days, Destiny’s bloody Valentines Day celebration, returns next week to Destiny 2. Players will be able to compete with their in-game partners and earn new rewards from Lord Shaxx.

The main mode for Crimson Days is Crimson Doubles. Players will form up — or matchmake — into a squad of two and venture into the Crucible in a round-based version of Clash. However, to make the event more doubles focused, players will gain increased ability generation when standing near their partner. Players who find themselves too far away from their partner will be revealed on the map and become easy prey for enemy squads.
