OTs-12’s Skill and buff tiles make her one of the better three star ARs in the game. Although she does not scale exceptionally well into the late game due to her low base Damage, she is a reasonably effective low cost unit for players who are trying to budget cores through the early and mid game.


Strong DPS Skill

OTs-12’s Assault Focus T Skill substantially increases her RoF, allowing her to output good DPS when she is provided with sufficient Damage buffs from accompanying SMGs.


Low Base Damage

OTs-12 has the second-lowest DMG among current ARs, which means that she scales somewhat poorly into the late game.

Poor Formation Buff Tile Placement

OTs-12 provides Damage and RoF buffs to SMGs in the upper two spaces in front of her, the former of which is very useful for Grenade SMGs in the early game. Like other RoF-based ARs later in the game, however, OTs-12 is generally forced into the bottom corner of a standard ARSMG formation due to poor scaling. Here, she can only buff the Main Tank SMG which will likely not have a grenade skill.

Full Analysis

OTs-12’s main downfall is in her stats, as her low Damage limits her late game scaling compared to many other ARs. Her exceptional base Accuracy also ends up being relatively unimportant in the late game, but that does not mean OTs-12 is completely without merit. Her formation buff -- which extends to the tiles directly in front and diagonally above and to the front of her -- provides a moderate 20% RoF and 15% Damage buff to affected SMGs. The RoF boost is inconsequential due to the low base ACC of SMGs, but the DMG buff is quite useful for SMGs with grenade Skills as it allows them to take further advantage of their Skill Damage multiplier.

OTs-12 has the Assault Focus T Skill, which at max level increases her RoF by 60% for 10 seconds after a 4 second Initial Cooldown. The massive RoF increase pushes her near the RoF cap, and combined with a relatively short Initial Cooldown allows OTs-12 to output more DPS than a fair number of other ARs of her rarity. She performs best when she receives DMG or Crit rate buffs as her Skill renders large RoF boosts unnecessary, however, it is advisable to provide OTs-12 with a minimal RoF boost so that she can reach the RoF cap. Like other RoF-based ARs, however, OTs-12 suffers from late game scaling issues which are only compounded by her low base DMG.

Overall, OTs-12 can be expected to perform quite well in the early and mid game due to her strong Skill and decent buff tile set. For players who are in need of a low core cost AR, OTs-12 is more than good enough provided she receives Damage and Crit buffs. Despite her early game power, however, OTs-12’s low base DMG ultimately caps her viability in the late game, and she should not be heavily prioritized for leveling over stronger 4 and 5 star ARs.

Team Options

Damage buffers

OTs-12 is best when teamed with units such as M4A1, UMP45, and MP-446 that can supplement her low base Damage.

Offensive SMGs

OTs-12’s formation buff is decent for offensive SMGs such as Vector, PPS-43, and Z-62. Their grenade Skills heavily benefit from the Damage boost, as it interacts very well with the Damage multiplier these Skills scale off of.


The OTs-12 Tiss (lit. “Yew Tree”) was designed as an alternative to the AKS-74U that was modified to chamber subsonic 9x39mm rounds. Despite a positive initial reception among Russian police forces and the Russian Interior Ministry, the OTs-12 was never mass produced and the project was eventually scrapped in favor of the OTs-14 Groza.
