Patch 1.1.1 won't have any downtime, but you'll need to use those keys quick before it arrives later this evening.
Anthem fans should expect an update today, as at 10:00 CST (16:00 BST, 17:00 CEST) the 1.1.1 patch will be rolling out, although this won't involve downtime. That said, you will need to close the game to download it, as revealed via the patch notes on Reddit.
Here we also find out that Elysian Caches are getting removed from the game today, so you only have a few hours left to use the keys. "They've always been planned as a temporary thing since there was a timer under the challenges. There is a chance that they'll come back again at some point," community manager Jesse Anderson explains.
