To unlock the Hypersonic BM in Build and Conquer on Roblox, you must register 100 hits on enemy ground units or buildings. This ballistic missile sits at the higher tier of the game's missile progression tree, directly following the SRBM, GLCM, and MRBM quest milestones.
Build and Conquer Missile Unlock Order and Requirements
Missiles in Build and Conquer unlock sequentially through combat quests at your military base. You cannot jump directly to the Hypersonic BM without finishing the preceding objectives.
| Missile Type | Unlock Quest Requirement |
|---|---|
| SRBM (Short-Range Ballistic Missile) | Hit enemy ground units or buildings 5 times |
| GLCM (Ground-Launched Cruise Missile) | Hit enemy ground units or buildings 12 times |
| MRBM (Medium-Range Ballistic Missile) | Hit enemy ground units or buildings 25 times |
| Hypersonic BM (Hypersonic Ballistic Missile) | Hit enemy ground units or buildings 100 times |
| Cluster Missile | Destroy 1,500 enemy buildings or units |
Each missile launch consumes in-game resources: cash, fuel, and steel produced by your Steel Works and delivered by industrial trucks. Recent game balance adjustments also enforce a 7.1-second launch delay between consecutive missile strikes.
Best Methods to Score 100 Hits
While the quest allows you to target either structures or mobile forces, community testing shows that targeting enemy ground units is significantly faster and more reliable than bombarding fortifications.
Targeting Ground Units
Targeting ground units bypasses heavily protected enemy bases. Player bases frequently run anti-air and anti-missile systems, where individual interceptors hold up to four defensive charges. Because interceptors can shoot down incoming strikes before they impact, strikes against well-defended bases often fail to register quest hits.
Deploying mobile ground artillery such as HIMARS alongside tanks allows you to scout open terrain, spot isolated enemy armor or infantry, and secure direct hits without interception.
Friendly PvP and Server Hopping
If an active server lacks deployed hostile units, players have two practical options:
- Cooperative PvP: Ask another player or friend in the server to deploy basic units one at a time in the field so you can score the required hit counts without fighting through defensive perimeter grids.
- Server Hopping: If the current server is passive or players remain entirely behind fortified boundaries, switch servers to find an active battlefield where opposing players deploy forces across mainland roads.
Hypersonic BM Combat Characteristics
The Hypersonic BM offers a distinct tactical upgrade over earlier ordnance in the weapon lineup:
- High Flight Trajectory: Upon launch, the Hypersonic BM climbs extremely high into the atmosphere before descending on the target coordinate at supersonic speeds.
- Low Interception Risk: Because of its steep angle and flight velocity, defensive anti-missile arrays have a significantly harder time intercepting it compared to standard cruise missiles and SRBMs.
- Base Bombardment: The missile is primarily suited for penetrating hardened player targets or AFK player bases where standard strikes fail against layered anti-air batteries.
Frequently Asked Questions
Do hits on player buildings count toward the 100 hits?
Yes, hitting enemy structures counts toward the 100-hit requirement. However, opposing anti-missile defenses can shoot down standard missiles before impact, which prevents the hit from registering.
What resources are required to manufacture missiles?
Launching missiles and interceptors in Build and Conquer requires money, fuel, and steel. Steel must be manufactured via your Steel Works facility and delivered to factories by logistics trucks.
What missile unlocks after the Hypersonic BM?
The weapon lineup features the Cluster Missile after the standard ballistic missile tree, which requires destroying 1,500 enemy buildings or units to unlock.
