Oren Koren is running a Steam playtest for the first major update to the solo action roguelite Don't Lose Aggro, which reimagines MMO raids for single-player play in the tank role. The playtest began on August 22 and requires registration through the Steam store page. The update's standout addition is a new companion class, the Summoner, which passively summons a skeleton minion every 3 seconds and can fight with up to 5 minions under command. Its active ability sacrifices one minion to restore the player's health. The party size also increases from 2 to 3 members, with companions now assigned Primary and Secondary roles, distinguished by whether they have active abilities. A new threat system replaces the previous health threshold system, where damage, heals, and taunts all generate hate, and a hate meter HUD shows the current status of the player and party members. A pull counter displays the number of enemies targeting the player during battle, granting experience bonuses of 5% to 20% based on that count.
The playtest is accessible by requesting access through the Don't Lose Aggro Steam store page, and the full patch notes are available on Steam for players who want details beyond the headline additions. The Summoner companion's active ability sacrifices one minion to recover 60 HP, a concrete number that distinguishes it from other companions. Secondary companions only have passive abilities, while Primary companions have both passive and active ones, creating a clearer division of party roles.
Oren Koren, the developer, is a player with 20 years of tanking experience in MMORPGs, which directly shaped the game's design philosophy. Don't Lose Aggro is available in early access on PC via Steam at a price of 1,000 yen and supports Japanese. The new pull counter system rewards players for attracting more enemies with experience bonuses ranging from 5% to 20%, reinforcing the tank's role as an attention-drawing front-line fighter. A target marker feature has also been implemented, allowing players to mark enemies for focused attack by the party, which adds coordination tools despite the all-AI party composition.
