All Random One Site is new, chaotic, and fast-paced VALORANT 5v5 limited time game mode. Here’s AROS, explained.
VALORANT is adding another game mode into the mix, All Random One Site! Here's everything you need to know about this chaotic addition.
All Random One Site in VALORANT
The nomenclature of this game mode is reminiscent of League of Legends' All Random All Mid (ARAM) game mode, so perhaps VALORANT's All Random One Site should be AROS.
AROS goes live with VALORANT Patch 12.00. This update also brings a new gun, the Bandit, some changes to Breeze, and balance changes.
Riot describes this as a "fast-paced 5v5 limited-time mode."

Your Agent will randomly change every round. There will be no duplicates per team, and you can still get Agents that you don't own.

There will only be one site on the map that will be activated. Other unused areas of the map are blocked with barriers. The active site is randomized per round and is revealed during the buy phase. The following maps are available:
- Abyss
- Ascent
- Breeze
- Corrode
- Pearl
- Icebox
- Sunset
- Split
Bind, Haven, Fracture, and Lotus are the maps absent from this game mode.
Agent abilities are fully granted each round for free. All abilities also recharge with a countdown.

Ultimate Orbs can be found around the map and grant 50% Ultimate Charge. Players start with 0% ultimate charge. Kills grant 50% ultimate charge, and killed players drop their accumulated charge.

Loadouts can be selected each round, and there is no economy. Weapons and loadouts escalate as the match progresses.
AROS as a limited-time game mode
All Random One Site is a limited-time game mode. However, the end date was not revealed as part of the announcement. We do know that Snowball Fight is making its exit, though.
We can expect AROS to be a part of the game mode rotation.
