Build and Conquer Roblox Hypersonic Missile Unlock Guide
Unlock Hypersonic BM in Build and Conquer on Roblox via the military quest line—SRBM, GLCM, MRBM, then hypersonic—and verify live requirements after BETA updates.
FAQ
Do I need the French Military Pack to unlock Hypersonic BM?
How many hits does Hypersonic BM take to unlock?
Can I grind missile quests on an empty mainland server?
Will slower SRBM and MRBM shots still count toward quests?
Build and Conquer [V0.1] on Roblox, by The Slop Company, is still in BETA with frequent updates. Hypersonic ballistic missiles (Hypersonic BM) sit at the end of the free Military quest chain—separate from buying the French Military Pack on the Roblox store. This page maps the public demo path, flags where videos disagree, and gives a checklist so you can verify your quest text after a patch.
What is the free unlock path for Hypersonic BM?
Roblox’s official description confirms you research and manufacture missiles, then fight on the mainland—but it does not publish quest steps. In English walkthroughs for place 103767961452227, creators open the Quests menu, select Military, and progress a hit-based chain that unlocks SRBM, GLCM, MRBM, and finally Hypersonic BM research—not a single button at the military base.
Per community reports from YellowHeadVin’s walkthrough 5itpkKyREZY (single source; not Roblox API text), the Quests → Military panel once showed hit counters in this order. FrlHXM1Sclw (September 2026) did not show quotas—treat the table as beta-era UI that may have changed:
| Quest name (as shown in 5itpkKyREZY) | Progress shown (single-source video) | Research unlocked |
|---|---|---|
| First Strike | 5/5 hits | SRBM Research |
| Precision Strike | 12/12 hits | GLCM Research |
| Strategic Reach | 25/25 hits | MRBM Research |
| Hypersonic Funnies | 100/100 hits | Hypersonic BM Research |
The same video mentions a later Cluster BM quest at ~1,500 hits—a separate end-game step, not required for Hypersonic BM. Quest text counts drone hits as well as missiles; see drones and UAV for how players produce and launch them.


How did the September 2026 hypersonic video differ?
YellowHeadVin’s earlier video FrlHXM1Sclw (summarized on community wikis around 2026-09-30) still shows the SRBM → GLCM → MRBM → Hypersonic BM order at the military base, but the narrator does not read kill quotas from the UI—only “destroy ground units or buildings.” That matches our rule: do not copy numbers unless your Quests panel shows them.
That demo recommends ground-unit kills as easier than leveling bases stacked with interceptors, uses one HIMARS plus tanks (HIMARS to spot movement, tanks to finish targets), and server-hops when the mainland is empty. The narrator’s opinion: lower-tier missiles can be intercepted; hypersonic shots arc high and feel harder to intercept—we label that as commentary, not a datamined stat.
Community pages also report viewer comments that missile quests changed after the September route. Treat any dated video as a BETA-era demo, not permanent law.

What loadout works for mainland quest grinding?
You need mainland access and units that can register hits without throwing away expensive volleys. Before hypersonic research, finish the 250 population military unlock and stand up fuel and steel production so HIMARS and tanks are actually available.
In FrlHXM1Sclw, the presenter deploys HIMARS alongside Leopard tanks, spreads units out, and uses HIMARS to check for enemy movement before committing. Our captured frame from that walkthrough shows the Deploy Forces window with HIMARS (noting GMLRS ammo) and Leopard-2A4 ready in storage—useful proof of the spotter-plus-armor idea, not a mandatory meta.

For broader mainland etiquette and PvP risk, see mainland capture and PvP. Only activate PvP when you accept that your home plot can be hit by drones and missiles—community guides stress defense before you chase quest tags on other players.
How do you fire Hypersonic BM after research?
Manufacturing and launch UI are separate from quests. In FrlHXM1Sclw, after unlocks, the top bar shows HYPERSONIC BM SELECTED with a target counter and ready missiles; the player queues GLCM and HYPER rounds and uses FIRE on a mainland base.

5itpkKyREZY also mentions a quality-of-life patch adding about 7.1 seconds between missile launches—we have not re-measured that delay in-game. Plan slower volleys when saturation matters for air defense.
Does the French Military Pack replace quests?
No—not equivalent. Roblox’s game-pass API lists B-Strike 1000 (SRBM), B-Strike 2500 (MRBM), B-Strike HGV (Hypersonic BM), and MdCN Launcher (GLCM) in the French Military Pack (399 R$). That is paid equipment, parallel to grinding quests. Community advice (single source) warns against buying passes only to chase quest unlocks you could earn free.
Compare pass value honestly in game passes worth it. If you bought Eastern European or French packs, you still need steel, fuel, and factory queues from military production setup.
What about missile reload, uranium, and “missing” ammo?
Public Roblox text is silent on reload recipes. Player reports collected on community wikis conflict: some say only hypersonic missiles reload while others do not; one thread mentions missing uranium even though uranium is not named in the official game description. We have not verified uranium as a build-menu resource.
Do not assume codes or other Roblox titles grant missiles—see Build and Conquer Roblox codes status and not Build a Country disambiguation.
How can you verify current quest requirements yourself?
Use this checklist after each Roblox Updated stamp on the official experience page:
- Open Quests → Military and screenshot the active quest line (name, hit counter, reward text).
- Confirm whether progress tracks drones or missiles only, or also ground units—match the sentence on your quest, not a wiki table.
- Note parallel quests (for example Cluster BM at 1,500 hits in 5itpkKyREZY) so you do not confuse them with Hypersonic BM.
- Deploy to the mainland with cheap hit sources first; if counters stall, check whether shots were intercepted versus missed.
- Compare your UI to air defense placement on the target base—heavy Sea RAM / PAC / Arrow stacks may slow building hits but still eat time.
- If nothing moves, server hop (demo method) or coordinate with a friend—reported friendly fire rules are not documented officially.
- After claiming Hypersonic BM Research, verify the node appears in your research/build flow before buying duplicate gear from game passes.
