Greetings, commanders!
Update 1.4.0 is the first of two major updates of Season 3. This update will be carried out at 07:00 AM on April 3, 2025, UTC time. At that time, the server will undergo update maintenance for approximately 5 hours.
Now let me introduce the main content of this update to you:
New Unit: Abyss
Abyss is a new Titan-class aerial unit, one of the most powerful units on the battlefield, capable of dealing devastating blows to ground units in a large area, and has multiple terrifying Techs.

Let's take a look at the Abyss Preview Video produced by MAG1, edited by Stoney, and voiced by RoosterPB.

Developer's note: Adding a new Titan Unit to the game is always scary. We do not yet know how the powerful Abyss will impact the balance of Mechabellum, and we are likely to adjust this unit in the coming weeks.
New Survival/Brawl Mode Unit: Mountain
Mountain is a new Titan-class unit that can be found in the Unit Reinforcement pool of Survival Mode and 4-Player Brawl Mode. Mountain's strong armor can block most attacks on the battlefield, and its multiple giant cannons can deal heavy blows to enemies from a great distance.

The following are the unique techs of Mountain:
- Mountain Plating: Blocks 1000 damage when attacked. The damage blocking effect increases with the Rank. And for each Rank, blocks an additional 1000 damage.
- Gun-launched Missile: Launches a rocket from its arm cannons every 15 seconds. The rocket has a range of 180, causing 22,500 damage to enemies within a 25m radius of the hit point. Damage increases by 22,500 per unit Rank increased.
- Saturation Bombardment: Increases range by 40, splash range by 3, and each attack fires 16 shells in succession, and shells spread out over a wide area, but increases attack interval by 300%.
- Extended Range Ammo: Increases range by 160, but decreases ATK by 75%.
- Photon Loop: Every 30s, covers the unit with a photon coating, decreasing damage received by 30% within 15s and grants immunity to Electromagnetic, Ignited, Acid, and Degeneration Beam effects.
- Smoke Bombs: Launches 10 Smoke Bombs towards the enemy every 45s. The Smoke Bombs have a max range of 200m and a minimum range of 100m. The range of units within the smoke is reduced by 35%.

Balance Adjustments
Hound
- Radius of Fire Extinguisher: 30 → 38
Arclight
- Health points 4635 → 4004 (-14%)
- [Armor Enhancement] HP bonus 35% → 50%
Developer's note: In the past few months, the pick rate and win rate of Arclight were higher than average. This change hopes to nerf the survival ability of Arclight while maintaining its efficiency against small units.
Mustang
- ATK 37 → 36 (-3%)
Developer's note: Mustang is the most picked unit besides Arclight. This adjustment will slightly reduce the efficiency of Mustang against high HP units while keeping its effectiveness against small units unaffected.
