Hell Let Loose Dev Brief #218 | Update 20 Notes (21st May 2026)
Hell Let Loose's Update 20 experimental branch is live, bringing a full armor overhaul, the Canadian Forces, and Juno Beach to test this weekend.
The armor changes alone make Dev Brief #218 one of the bigger experimental patches Hell Let Loose has seen in a while. The Update 20 experimental branch went live today, and the headline is a complete rework of how tanks deal and absorb damage across every faction.
The new system introduces tiered health categories and a percentage-based armor resistance model, so a Light tank shell bouncing off a Tiger's front hull now has a mechanical reason behind it rather than just feeling arbitrary. The Panther has been repositioned as a Medium-health Heavy, making it cheaper and faster to field but squishier than a Tiger, while the Sherman Firefly gets a big damage bump to cement its anti-armor role. The Sherman Jumbo 75 has been pushed toward anti-infantry work with extra HE rounds and a significantly lower fuel cost. I think the Panther change in particular is smart design; the Tiger/Panther distinction has always felt muddier than it should.
Beyond tanks, select vehicles are getting smoke launchers, AT rocket counts drop from their current value to 2 (with damage rising from 330 to 420), and both Tank Commander and Crewman now carry a hammer for building and salvage. The full Update 20 changelog drops in June. Here's everything that changed.
Full Patch Notes
Welcome everyone to the Update 20 Experimental Branch. After our previous test earlier this month on Juno Beach, we are returning this weekend with our Update 20 Exp Branch complete with our latest map Juno Beach, the Canadian Forces, and a host of armor changes that we cannot wait for you to experience.
For more information on Juno Beach and the Canadians, head over to Dev Brief #217. In this blog we will dive deeper into some of the upcoming armor changes that you can expect in Update 20 and during your testing this weekend.
We are also excited to reveal some of our brand new War Correspondents joining the programme. Be sure to read on to find out more.
Armor Changes
With a lot of tanks having new health values, new damage outputs and the damage resistance system in place, the following rules will apply when landing shots on armor hull:
- Heavy damage on Heavy health = 3 shots to the front, 2 shots to the side and rear.
- The Firefly, with its increased damage output, will only need 2 shots to the front on other Heavies
There are also a number of changes being made to specific tanks. The following are a handful of tanks being balanced to fit these new rules. All tanks have been balanced but here is a small preview of what is to come:
German Forces
Panther
This balance change is to make a clear distinction between the Tiger I and the Panther. While both classed as Heavy tanks, the Panther has kept its damage output as a Heavy but now has the health as a Medium. These changes are also reflected in its fuel cost and armor values detailed later on.
- Hull Health - 1170 → 930
- Turret Health - 990 → 850
- Tracks Health - 910 → 730
- Engine Health - 550 → 480
- Turret Rotation - 12 → 10
- AP Ammo Count - 40 → 45
- HE Ammo Count - 40 → 30
- Fuel Cost - 600 → 430
- Cooldown - 600 → 420 seconds
British/Canadian
Sherman Firefly
Similar to the Panther, the Firefly has had big adjustments. It now has the health of a Medium tank and changes to its armor values, however has seen a large increase to its damage. This is to reflect its role as a tank killer.
- Hull Health - 1180 → 900
- Turret Health - 1020 → 830
- Tracks Health - 920 → 710
- Engine Health - 580 → 460
- Turret Rotation - 10 → 12
- AP Damage - 850 → 920
- Fuel Cost - 600 → 560
- Cooldown - 600 → 630 seconds
US
Sherman Jumbo 75
During gameplay, players will still tend to lean towards the 76 version of this tank. With its adjusted values and cheaper cost, the 75 is now more of a point control menace. Its high HE count and large HE explosion radius, this tanks primary function is anti-infantry. If players aim to destroy enemy tanks, the 76 is still the go to.
- Hull Health - 1170 → 1230
- Turret Health - 1050 → 1020
- Turret Rotation - 14 → 12
- AP Damage - 700 → 710
- HE Ammo Count - 60 → 65
- Fuel Cost - 600 → 410
- Cooldown - 600 → 430
We will add even more information to the Update 20 Changelog, so be sure to tune in once it drops in June.
Armor Values
We have also made changes to armor values on tanks. These changes are to better reflect their real world counterpart but balanced within the world of Hell Let Loose:
Heavy Tank
Top of Heavy turrets decreased. Lights can now pen this armor.
- Panther updates:
- Side hull decreased. Lights can now pen this armor.
- Turret front increased. Only Heavies can pen this armor.
- Turret sides and rear decreased. Lights can now pen this armor.
- Front hull decreased. Mediums can now pen this armor.
- Side hull decreased. Lights can now pen this armor.
- Turret front, side and rear decreased. Mediums can now pen this armor.
Medium Tank
- Side hull of all Medium tanks decreased. Lights can now pen this armor.
- Panzer IV updates:
- Turret sides and rear decreased. Lights can now pen this armor.
Light Tank
- Front hull on all lights, not including the T-70, decreased. Lights can now pen this armor.
Recon Tank
- All armor on Recon tanks have been decreased slightly. AT launchers should destroy these tanks with 1 shot.
Armor resistance changes
All tanks now feature a new Armor Resistance system. Armor thickness now provides a percentage based damage reduction depending on its thickness. The values have been updated from feedback.
- Heavy frontal armor now provides a 32% resistance, up from 25%.
- Medium frontal armor and Heavy side armor now provides a 16% resistance, up from 15%.
- Light frontal armor, Medium side armor and all rear armor now provides a 8% resistance, up from 5%.
Fuel Balance
With the new resistance system and balance changes, a fuel cost balance was required. This involved updating armor fuel costs as well as other vehicles. All fuel updates apply to each category of vehicle, across all factions. The new values for vehicles are:
Half Track
- Fuel Cost - 300 → 150
- Cooldown - 300 → 240 seconds
Trucks
Supply
- Fuel Cost - 100 → 70
- Cooldown - 90 → 75 seconds
Transport
- Fuel Cost - 100 → 50
- Cooldown - 90 → 60 seconds
Jeep
- Fuel Cost - 80 → 30
- Cooldown - 300 → 180 seconds
Salvage Return Balance
Now that most of the vehicles have had a fuel balance pass, the amount of fuel and time taken to salvage have been updated. Here are the updated values:
- Heavy - 60 fuel in 12 seconds.
- Panther and Jumbo 75 - 40 fuel in 10 seconds.
- Medium - 20 fuel in 8 seconds.
- Light - 15 fuel in 6 seconds.
- Recon - 10 fuel in 4 seconds.
- Half Track - 15 fuel in 6 seconds.
- Truck - 5 fuel in 3 seconds.
- Jeep - 5 fuel in 3 seconds.
Smoke Launchers
We’re excited to announce that a select few tanks will be gaining a new weapon; smoke launchers.
Set in the Commander/Spotter seat, players will now be able to fire smoke grenades, pressing Spacebar on PC and Right Bumper/R1 on controller, for some extra cover.
Smoke launchers can be different on a tank by tank basis. Some fire internally, some fire externally and some generate smoke from their exhausts. We’ll reveal the full list on the Update 20 changelog, however test them out this weekend and let us know your thoughts!
Shell Unloading
As previously mentioned in Dev Brief #217, all tanks now feature the option to unload a fully loaded shell. If you are in a situation where you have the wrong shell loaded, you can now simply unload it. No more firing the shell and revealing your location.
Tank Commander and Crewman Loadouts
For each faction, both the Tank Commander and Tank Crewman have had all their loadouts updated meaning that they both now carry a hammer. This will allow them to help out in building structures and have an easier time salvaging vehicles as you play.
Anti-Tank Updates
We have also made changes to the Anti-Tank role, with the rocket count reduced to 2 whilst damage increases (330 → 420), as well as the Anti-Tank Gun for all factions seeing a significant damage increase (400 → 535).
Community Update
There is loads happening in the community currently. First up, tomorrow we will be livestreaming when the Exp Branch goes live over on the Hell Let Loose Official Twitch showing off the new update to the community. Be sure to jump into the chat and get chatting!
