Blockade Battlefront X18 Overview & Requirements
The G-Toilet X-18 (often referred to as the G-Man X18) is one of the most coveted Special Titans in the Roblox hit ST: Blockade Battlefront. Known for its incredible damage output, high health pool, and a signature charge attack that features zero cooldown as long as you land consecutive hits, unlocking this beast is a major milestone for any endgame player.
To acquire the G-Toilet X-18, players must collect three distinct core items that drop exclusively in the game's Zombie Mode.
Video Highlights:
- Learn the visual cues of the glowing bluish aura on the ground when a core spawns.
- Understand why the Wave 7 reset strategy is the most efficient method for solo grinders.
- See the tactical deployment of the Upgraded Camera Strider for fast mob clearing.
The Three Required Cores
To unlock this Special Titan, you must farm Zombie Mode to obtain these three specific items:
| Core Name | Visual Appearance | Primary Source | Drop / Spawn Chance |
|---|---|---|---|
| X-18 Core | Glowing blue/purple energy core | Zombie Mode ground spawn | 1 in 4,000 (0.025%) |
| Energy Core Base | Dark metallic casing structure | Zombie Mode ground spawn | 1 in 4,000 (0.025%) |
| Green Energy Core | Radiant green central core | Zombie Mode ground spawn | 1 in 4,000 (0.025%) |
Always craft and equip your G-Toilet X-18 on a public server. A known bug can prevent the Titan from saving to your permanent inventory if unlocked and activated inside a private server.
Fastest Farming Strategies for X18 Cores
Because the spawn rate for each core is incredibly low (1 in 4,000), relying on long, full-clears of Zombie Mode is highly inefficient. Instead, veteran players utilize targeted speedrunning strategies to maximize the number of waves completed per hour.
Strategy 1: The Solo Wave 7 Reset (Fastest)
- Best For: Solo players looking for pure speed.
- Core Concept: Run Waves 1 through 7, scan the entire map for glowing blue auras, reset, and repeat.
- Optimal Units: Upgraded Camera Strider or Alarm Clock Man.
Strategy 2: The Full Wave 13 Team Clear
- Best For: Coordinated groups wanting the Zombie Mode victory badge alongside drops.
- Core Concept: Run a balanced lineup all the way to Wave 13 to secure rare progression materials.
- Key Units: Titan Clockman, Large Clockman, and Speaker Helicopter.
Recommended Class Loadouts for Farming
Using the right units determines how fast you can clear the early waves. Below is the meta setup for both beginner and advanced setups:
| Setup Tier | Recommended Character | Weapon/Skill Priority | Strategy Focus |
|---|---|---|---|
| Pro Setup | Upgraded Camera Strider | Fly high, gather mobs, and use R ability | Fastest solo clear times, high mobility to scan the map. |
| Budget Setup | Alarm Clock Man | Buy Flamethrower & Double Shotgun | High AoE damage for early waves; cheap to execute. |
The cores do not drop directly into your inventory from enemy kills. Instead, they spawn randomly on the ground during a wave, emitting a distinct glowing bluish aura. You must walk over and collect them manually.
Step-by-Step: How to Farm and Save Cores
Follow this exact step-by-step procedure to ensure you farm efficiently and never lose a rare core drop due to a premature reset.
Select Casual Zombie Mode
Navigate to the main lobby. Select Classic Mode, choose Casual, and load into Zombie Mode. Avoid private servers for farming if you want to be completely safe from inventory saving glitches.
Clear Early Waves & Scan
Use your Upgraded Camera Strider or Alarm Clock Man to quickly defeat the incoming infected waves. While fighting, zoom out or go into first-person mode to scan the entire arena floor for a glowing blue aura.
Secure and Save the Core
If you spot a core, walk over it to pick it up. Crucial: You must complete the active wave you are currently on. If you reset or exit the lobby before the wave officially ends, the core will not save to your inventory.
Reset at Wave 7
If no cores have spawned by the end of Wave 7, press Esc and reset your character. Re-enter the lobby and queue back into Zombie Mode to restart the cycle.
Beating Zombie Mode: Wave 12 & 13 Strategy
If you choose to run the full 13 waves for the ultimate challenge and the completion badge, you must coordinate with a team to survive the final onslaught.
Boss Tactics: Zombie Titans
- Zombie Upgraded Titan Speaker Man (Wave 10): Immune to normal attacks. You must target the specific weak points (like his hand) that appear every 60 seconds and deal 1,500 damage to break his defense.
- Zombie Upgraded Titan TV Man (Wave 12): Features heavy armor. During phase 2, he takes only 25% damage, and in phase 3, a tiny 2.5% damage. Wait for him to scream, then shoot directly into his open mouth to trigger a Break Effect for 4x damage.
Team Lineup for Wave 13 Clears
| Role | Character | Key Action |
|---|---|---|
| Time Control | Large Clockman | Use Time Stop to freeze dangerous infected swarms. |
| Healer / Support | Speaker Helicopter | Equip the Repair Gun to keep Titan Clockman healthy. |
| DPS / Carry | Titan Clockman | Coordinate so only one player deploys him; protect him from being targeted. |
Beating Wave 13 not only rewards progression materials but also gives a chance for the elusive Green Energy Core to spawn directly.
