Call of Duty: Modern Warfare 4 Open Beta Dates and Start Times Detailed

Players preparing for the upcoming launch of Call of Duty: Modern Warfare 4 can look forward to testing the game through an open beta split across two weekends. According to recent guides, the beta periods will provide an early look at both multiplayer features and a sample of the campaign before the full title arrives this October.

The first weekend is designated for early access pre-orders and runs from August 21st until August 25th. Notably, Game Pass does not count for early access participation this year. Following the first weekend, a second open beta will open to all players, running from August 28th through September 1st.

Expected regional times include 10:00 AM PDT for North America, 7:00 PM CEST for Europe, and 2:00 AM JST on Saturday for Asia and Oceania regions. Guides note that further clarification on exact start times will be provided once official confirmation is received.
