Developer Treyarch has released a minor new Call of Duty: Black Ops Cold War update offering movement tweaks alongside crash fixes.

Following the Cold War Season 1 update that went live last week, a small patch is now available across all platforms packing some changes and fixes in both Multiplayer and Zombies mode. As for movement in Cold War multiplayer, the new update reduces penalties to speed and jump height when landing from a jump.
