The latest patch for Metal Gear Solid V: The Phantom Pain adds a brand new online survival mode that can be played on all platforms. Somewhat buried in the official patch notes is mention that the new Survival Mode is available on PlayStation 4, Xbox One and PC – players must use a consumable item called “survival tickets” to access this new mode. Each player is given 10 survival tickets per weeks during weekly maintenance and the free tickets do not rollover from week to week. By purchasing the “Cloaked in Silence” expansion DLC for $4 players can try out survival mode as much as they’d like – in addition to the new maps & Quiet skin.

Here are the official patch notes from Konami:

[SURVIVAL]
– New “SURVIVAL” mode has been added.
*You can play SURVIVAL even if you don’t have the EXPANSION PACK “CLOAKED IN SILENCE”, as long as you have a minimum of one (1) SURVIVAL TICKET.
*10 (non-stackable) SURVIVAL TICKETS are distributed during the regularly scheduled maintenance each week. SURVIVAL TICKETS do not carry over week upon week.
