The Retcon is the most divisive class in Deep Rock Galactic: Rogue Core. Some players swear she's the strongest Reclaimer in the game; others find her frustratingly inconsistent. Both camps have a point. Her ceiling is genuinely high, but she demands more deliberate build planning than any other class before you even drop into a mission.
How does Retcon's Rewind Time ability work?
Rewind Time is the defining mechanic of the entire class. When you activate it, Retcon locks in her current position, health, armor, ammo, and grenade count as a snapshot. You then have 20 seconds to act freely before automatically snapping back to that exact state and location. You can also trigger the return early by pressing the ability again.
The cooldown sits at 75 seconds, so each activation is a meaningful decision rather than a panic button you spam.
The practical implication is that Retcon plays conservatively until Rewind Time is ready, then becomes near-unstoppable for a short burst. Before activating, you want as much armor, health, and especially grenades saved up as possible. That stockpile translates directly into how much damage you can output during the window.
What are Retcon's other abilities?
Rage is a class skill that charges up as Retcon takes hits. Once full, activating it grants +100% damage and +30% Pickaxe Speed for 12 seconds. The Rewind Time window is the safest moment to stack Rage because any damage you absorb during that period gets erased when you snap back.
Contingency Plan is a passive that triggers once per mission. If the entire team wipes, Retcon automatically revives with full armor and health. It won't save a solo run repeatedly, but in co-op it can flip a failed mission into a completed one.
What Bio Booster decks does Retcon have?
Retcon has two Bio Booster decks to choose from: Recklessness and All In. Your deck choice shapes the entire build direction, so this decision matters before you even look at weapons.
The Recklessness deck leans hard into melee and close-quarters brawling. All In rewards weapon-switching and sustained gunfighting. Both are viable, but they require completely different weapon selections and upgrade paths.
What Workbench upgrades should you take for Retcon?
Retcon's Workbench upgrades all modify Rewind Time directly:
Horology is the most straightforward pick since extending the 20-second window by 15% gives you more time to output damage. Temporal Buffer pairs well with the Melee Berserker build because the Stoneskin cushion lets you wade into enemies without burning through your pre-activation health reserves.

Best Retcon builds
Retcon's builds are not something you improvise on the fly. The weapon you pick at mission start sets the direction for everything else, and pivoting mid-run is costly. Decide your build path before you drop.
Build 1: Weapons Specialist
This build turns Rewind Time into a sustained damage window by pairing high-output weapons with upgrades that extend and amplify the burst. The core idea is to find the Heavy Weapons crate (available at round-end rewards or as a mid-run pickup) and unleash it during Rewind Time. Weapons like the Deepcore 40mm PGL grenade launcher or the Breach Cutter can clear entire swarms in the 20-second window.
Until you find a Heavy Weapon, focus on hoarding grenades. The Cryo grenade is the best option for Retcon since she has better grenade economy than other classes, and frozen enemies are far easier to deal with during the burst window.
For primary weapons, prioritize large magazine size, high damage, and fast fire rate. The Bolt-Tec "Decker" submachine gun and the Drak-25 Plasma Rifle both fit this profile well.
Workshop upgrades here are better spent on weapon enhancements rather than class ability modifiers. Once deck swapping unlocks, consider replacing the Recklessness melee deck with the Falconer's Mixed Tactics deck for additional ability cooldown reduction.
Elemental stacking also pays off in this build. Match your Expenite elemental upgrades to your weapon's damage type for compounding effects.

Build 2: Melee Berserker
The Melee Berserker build centers on the Recklessness Bio Booster deck and specifically the Axe Out upgrade, which doubles melee damage for 8 seconds after emptying a weapon magazine. The gameplay loop is straightforward: dump a magazine with the Jury-Rigged Boomstick shotgun (or another low-capacity weapon), trigger Axe Out, then go to town in melee range.
This build requires specific Enhancement selections before the mission starts. Pommel Rebalancing, Handle Grip, and Skull Crusher Enhancements are the backbone for meaningful power attack and melee damage output.
The cold damage loop here is genuinely effective. Cryo grenades, Cold Blood, and Subzero Range combine to keep enemies frozen and helpless while Crippling Strike adds another layer of crowd control through stuns. Vampire keeps you alive by converting kills into healing, which matters because this build intentionally operates with little to no armor.
After testing this build across multiple runs, the Melee Berserker holds up well through Depth 3. At higher clearance levels, the lack of armor requires tighter play and more deliberate use of Rewind Time as a safety valve rather than an offensive tool.

Which Expenite upgrades work best on Retcon?
Retcon benefits more from damage-on-hit upgrades than almost any other class because her abilities incentivize taking damage. Three Expenite upgrades stand out as particularly strong picks regardless of build:
Adrenaline Charger deserves special attention. Reducing your cooldowns by taking hits directly addresses Retcon's biggest weakness: the 75-second Rewind Time cooldown. More hits mean more resets, which means more burst windows per mission. For a full breakdown of every available upgrade and rarity tier, the Expenite upgrades guide covers the complete list.
Retcon in co-op: how does she fit the team?
Retcon's Contingency Plan passive makes her a strong pick for co-op specifically because a single wipe no longer ends the mission automatically. In a 4-player squad, she functions as a soft safety net while also contributing burst damage during Rewind Time windows.
That said, her role in a team isn't to tank or provide consistent support. She's a burst damage dealer who plays conservatively between windows. If your squad already has a Guardian holding the frontline, Retcon can focus entirely on building toward her power spikes without needing to cover defensive gaps.
