- This article is about the deployable device in Mizuki & Caerula Arbor. For the buff, see Barrier.
The Barrier is a deployable device in the Integrated Strategies game mode of Arknights, featured on Mizuki & Caerula Arbor where two of them are available in operations as long as the player has the 
Support Riot Pile.
A makeshift obstacle made from what appears to be an underwater cage, Barriers boast good HP and can block up to 4 enemies, making it suitable for delaying enemies' advance. However, its defenses are lacking and unlike Roadblocks, Barriers do not reroute enemies.
