Call of Duty 6 has been given a huge new update by Treyarch.

The January 3 update introduces the Squid Game crossover to on PS4, PS5, Xbox Series X|S, Xbox One and PC.

As you can see from the patch notes below, this includes three new multiplayer modes, including Red Light, Green Light, where you'll need to watch your step.

That's on top of a new High Roller MP Wildcard, which allows users to equip four Scorestreaks in multiplayer.

Controversially, however, the new update also adds a Squid Game event pass, which fans will have to pay extra money for.

If you do purchase the event pass, you can unlock Operator Skins, weapon blueprints and lots more.

Squid Game Moshpit (NEW)

Fire up the Squid Game Moshpit including Team Deathmatch, Domination, and Hardpoint with a twist as players gain access to three important Squid Game-themed features.

Red Light, Green Light Scorestreak: Is the fight getting too hectic for you? Stop the enemy in their tracks with this Scorestreak that calls "Red Light," commanding all enemy players to stop moving or risk elimination.

Piggy Bank: Eliminated players have a chance of dropping a Piggy Bank that awards a small score boost when picked up. For a bigger payday, watch for the Mega Piggy Bank. Every elimination adds additional score to the Mega Piggy Bank, so once it drops, fight for it to acquire all the deposited score within.

Roulette Handgun: The epitome of high risk, high reward. The Roulette Handgun spawns in the center of the map; grab it to activate a permanent UAV effect while wielding it and land one-shot eliminations against enemies, earning more than double the normal score to help you obtain Scorestreaks more quickly. The catch? Your location will be marked for everyone to see, and every shot has a chance to blow up the weapon, taking you down with it.
