In Last War: Survival, the Overlord Gorilla is a powerful squad companion that unlocks after reaching a specific bond rating. Overlord Gorilla is not a hero, but it’s a long-term squad companion designed to grow alongside your progress. When attached, it boosts your squad’s power with passive stats and contributes to battles with its own skills. You’ll unlock the Overlord Gorilla near the end of Season 2, often around Day 89 on most servers.
The Overlord system kicks off with a four-day, radar-driven rescue storyline. Once it’s done, you’ll need to start using key resources like Training Guidebooks, Training Certificates, Bond Badges, and Skill Badges to move through training and promotion milestones. These items are essential, but they’re also limited by in-game timers and store refreshes. Instead of waiting for weekly resets, you can use LootBar to top up key materials and keep your Overlord’s growth on schedule.

What Is the Overlord Gorilla?
The Gorilla Overlord isn’t another hero you slot into your lineup. It’s a squad companion you unlock through bond rating progression and assign to one of your squad.
It supports your squad in two ways:
- Passive boosts – It adds bonus stats to your squad through Overlord attributes, helping overall strength.
- Combat skills – Once deployed, the Gorilla brings its own set of skills into battle, offering both damage and utility effects.
While you may notice a jump in displayed squad power once deployed, keep in mind that actual performance still hinges on your Tech Research, Troop Tier, Gear Level, and Hero Synergy. The Gorilla is a high-value asset, but it’s designed to support your existing progress.
Overlord Gorilla: Rescue Timing and Unlock Path
The Overlord Gorilla is available around Day 89 of Season 2. This event appears as a radar-style mission where you assist in healing the injured Gorilla using collected supplies such as water, food, and medicine. It takes four days to finish and moves forward step-by-step each day. Once you complete the rescue, you unlock the Overlord interface, including :
- Overlord Base: The main hub for training and promotions.
- Tactical Institute: Source of Training Guidebooks.
- Overlord Truck Missions: Extra rewards and materials tied to Overlord progression.
Your Real Goal: Reach “Rookie Partner I”
Unlocking the Gorilla Overlord system is just the beginning. Deploying the Gorilla into battle requires reaching the bond rating "Rookie Partner I". This is the first milestone where you can assign the Overlord to a squad and activate its full combat skills. To reach it, you need to level up two key systems at the same time:
- Specialized Training – made up of three separate trees: Joint Attack, Defense Support, and Survival Training.
- Bond Promotions – which require Bond Badges to advance each tier.
Once it hits that milestone, you’ll unlock the Gorilla’s active skill set, which includes combat abilities like AoE damage, buffs, and crowd control, depending on how you build it. All three specialized training paths, Joint Attack, Defense Support, and Survival Training, must be leveled up together.
Specialized Training: Your Core Progression System
Inside the Overlord Base, you'll find three key training lines. To strengthen and deploy Overlord Gorilla, you’ll need to invest in three specialized training paths:
- Joint Attack – Boosts both hero and Gorilla attack stats.
- Defense Support – Increases defense for both your heroes and the Gorilla.
- Survival Training – Focuses on max HP and tankiness.
Each line must be leveled up using Training Guidebooks and Training Certificates and train all three lines evenly. If one of the three falls too far behind, it will block your ability to promote the Overlord Gorilla. If you ever find yourself stuck just short of the next milestone, use LootBar to grab the exact number of guidebooks or certificates missing. It’s especially helpful when trying to time a promotion with an event or avoid a weeklong wait from refresh limits.
Promotion Overlord Gorilla System: How Deployment Works
Training your Gorilla Overlord is just half the battle, to deploy Overlord Gorilla into combat you need to increase its bond rating to Rookie Partner I.
Bond Rating & Promotion Path
The Overlord Gorilla’s bond rating progresses through multiple tiers:
- No Rating (starting point)
- New Partner I → New Partner X
- Rookie Partner I (This is where deployment becomes available)
Training Checkpoints for Promotion
To unlock each promotion tier, your specialized training needs to meet these level goals:
- Level 50 in all 3 training lines to unlock promotion from No Rating ➜ New Partner I
- Level 100 in all 3 lines to unlock promotion from New Partner X ➜ Rookie Partner I
Total Materials to Reach Rookie Partner I
Before your Gorilla can join your squad, you will need the following total materials:
| Resource Type | Total Required |
| Training Guidebooks | 300,000 |
| Training Certificates | 1,800 |
| Bond Badges | 24 |
Where to Get Overlord Materials
- Radar Missions (Overlord)
These daily tasks give solid Overlord rewards. Always prioritize them.
- Armed Truck Missions
Run these regularly to get chests with useful Overlord materials.
- In-Game Store (VIP, Alliance, Campaign)
Check these weekly for Guidebooks, Certificates, and Bond Badges.
- Overlord Growth Boost
This limited-time event offers a ton of free materials just by logging in and completing simple tasks.
- Overlord Training Battle Pass
The Overlord Training Battle Pass is one of the best ways to stock up on Overlord resources, with rewards like Guidebooks, Certificates, and Skill Badges that speed up your progress.
Overlord Skills
After reaching Rookie Partner I, you can assign and upgrade your Gorilla’s skills using Skill Badges earned from Truck Rewards, Supply Chests, and Store Items. Brutal Roar should be your first focus due to its strong debuff. Then invest in Overlord’s Armor to improve durability, followed by Furious Hunt for damage potential. Riot Shot is less of a priority, and Expert Overlord unlocks automatically at level 51; it doesn’t require any upgrades.
Conclusion
The Overlord Gorilla is a powerful addition to your squad, but unlocking and deploying it takes planning. Focus on training all three skill paths evenly, use your Bond Badges carefully, and save Skill Badges for skills that matter (like Brutal Roar and Overlord’s Armor). If you need a little extra push at critical material milestones, consider Last War Top Up through LootBar to stay on pace, especially during big events or promotion milestones. With time and strategy, your Gorilla will become a game-changing support unit.
