Exciting news for Call of Duty fans: the open beta for Modern Warfare 4 is just around the corner, kicking off on August 28th and running until September 1st, 2026. To participate, all you'll need is an active Nintendo Switch Online subscription and a Nintendo Account - no pre-order necessary.

This announcement comes as a welcome surprise, especially given that pre-orders won't be required to join in on the beta action. However, it's worth noting that while beta early access has been confirmed for PC, PS5, and Xbox Series X|S, the Switch 2 will not be included in this initial rollout.
