How to Unlock T11 Troops in Last War (Step-by-Step Guide)

T11 Troops are a game-changer in Last War: Survival, but unlocking them isn’t as simple as clicking “train.” They are locked behind a complex progression path that includes building a new facility, acquiring new resources, and completing high-level research.

In this guide, you’ll learn every single step required to unlock T11 Troops—from your first HQ upgrade to training your first Armoured Trooper or Assault Raider.

How to Unlock T11 Troops in Last War (Step-by-Step Guide)

Step 1: Meet the Prerequisites

Before you can even begin unlocking T11 troops, you must meet these three non-negotiable requirements:

1. Reach Season 4 Off-Season

T11 content is only available after Season 4 ends and you enter the Off-Season. This acts as a game-wide trigger that activates the Armament Institute for eligible players.

🔔 Important: If you’re still in Season 4, no progress can be made toward unlocking T11s—focus on preparing instead.

2. Upgrade HQ to Level 27

Your Headquarters must be at level 27 or higher to unlock the Armament Institute. This unlocks the new research facility critical for T11 progression.

3. Upgrade One Barrack to Level 35

Although not required to unlock T11 troops, a Level 35 Barrack is essential to train them once unlocked.

⚠️ Cpt Hedge’s Tip: This upgrade is expensive and time-consuming—start your level 35 Barrack early while doing the research.

Step 2: Build the Armament Institute

Once you’re in the Off-Season and have HQ 27+, the Armament Institute becomes available to construct.

What You Need to Know:

• Single-Level Structure: No upgrades required.
• Location: Appears automatically in your building options.
• Purpose: Hosts all Armament Research, which is the core requirement to unlock T11 troops.

This building doesn’t train units—it unlocks them through research.

Step 3: Complete All Armament Research

There are four research branches inside the Armament Institute:

1. Helmet
2. Armor
3. Weapon
4. Boots

You must complete all four to 100% to unlock the T11 troops.

Armament Research Details:

• Each branch requires Armament Materials (every level)
• Every 5th level also requires an Armament Core
• Progression is linear: you must complete Helmet research first to unlock the others
• Research levels increase Troop Power slightly with each upgrade

Timeline Expectation:

Expect to spend several weeks to months completing all four branches, depending on:

• Your troop power
• How efficiently you farm Restricted Area bosses
• Whether you buy packs or play free-to-play

Unlock Confirmation

Once all four research paths in the Armament Institute hit 100%, and you have at least one Barrack at level 35, you will be able to:

• Train T11 units (choose between Armored Trooper or Assault Raider)
• Begin star upgrades for Armament Research
• Access T11 passive skills and stat benefits
