Rainbow Six May 25 patch to feature ACS12 buffs, major gadget glitch fix

Rainbow Six: Siege’s test server (TTS) is getting more updates, with a patch being shipped on May 25 buffing the ACS12 shotgun, and fixing a major bug affecting all gadgets.

Operation Steel Wave is currently being tested out on the TTS before hitting live Rainbow Six servers. However, Ace, Melusi, and the new House aren’t the only things Ubisoft are looking at adding in the next major update.

The ACS12 shotgun is being buffed, and major bug fixes implemented with the new update are also being squashed as we speak, to ensure a clean launch of Rainbow Six’s latest expansion.


Alibi and Maestro’s ACS12 is getting a damage buff.

ACS12 for Maestro and Alibi buffed

The ACS12 is arguably the worst shotgun in the game. Only available to Italian defenders Maestro and Alibi, there was no place in the game for the automatic shotty. It only tickled attackers, and was rather difficult to control.

However, with a damage buff in the recent patch, maybe there’ll be some niche use for the ACS12. With its damage up to 59 from 41, it’s a significant buff ⁠— almost as big as the nerf to the TCSG12 a couple of weeks ago.

Don’t be swapping your Alda or your Mx4 Storm for the ACS12 just yet. It’s still, for all intents and purposes, a strictly worse weapon. It’s just not as bad as it once was.


Invisible smokes, flashes fixed

The Operation Steel Wave patch brought a host of problems for gadgets in Siege. Flashes, smoke grenades, and most particle effects were completely invisible, making some operators like Ying completely useless.

Ying’s Candelas will now work as intended.

According to the patch notes, this bug has been fixed. They were listed as being “missing or corrupt,” but should deploy normally from now.

So, if you are playing Ying, Smoke, or another operator who relies on flashes or smokes to get the job done, you shouldn’t be held back any longer.

On top of the ACS12 buffs and the gadget bug fix, there were also some small fixes to the new House. Some of the lighting has been touched up, as well as certain spawns leading to players dying instantly upon loading in.
