Call of Duty: WW2's free community event ahead of the release of its Resistance DLC map pack hands players new weapons, a new division and plenty of XP boosts, but two time-limited game modes are the most interesting additions. For two weeks from Tuesday (January 23), you'll be able to log on and play silly party game Prop Hunt, where one team has to hide from the other by disguising themselves as background items in a map, like a table or a battered chair. I've had a lot of fun with it in other games, and I can't see why this would be any different.

For the same period, you can also play Demolition, the classic Call of Duty game mode that didn't make the cut for WW2. One team has to blow up bomb sites while the other defends and diffuses any explosives the attackers manage to stick down. It's a bit like Search and Destroy, except you can respawn. You'll be able to jump into a Demolition 24/7 server for the duration of the event.
