They don't make 'em like this anymore.

This review was machine-translated from the Japanese original. Numbers are checked against the original; if the wording reads oddly, the Japanese version is authoritative.

When thrown in an arcing trajectory, it detonates on impact, scattering child grenades that bounce and cause chain explosions, a “area suppression type” heavy MIRV grenade. Manufactured by Vladof, it disperses a multi‑stage explosion of 1 main + 4 children + 8 bouncing grandchildren in a single throw. It’s a satisfying single throw when you want to clear a group of enemies.

🧩 Red Text source The name Blockbuster means “big hit / huge explosive” and is a double reference to the former major video rental chain Blockbuster. “They don’t make ‘em like this anymore.” (unverified) is a nostalgic tongue‑in‑cheek flavor referencing old video rental stores and classic explosives. The match between the name and effect (“huge explosion”) is clear, but direct quotation from a specific work as verifiable primary information is unverified. The external source is (unverified) (will be added when identified).

What kind of grenade? (Beginner’s perspective)

• MIRV-type grenade manufactured by Vladof. It flies in an arcing (large curve) trajectory, so a bit of practice is required to get the throwing feel
• On impact, it generates a 100% element splash explosion + 4 child grenades
• Each child lands and creates 2 bounce grenades → they explode each time they bounce
• One throw with “1 main + 4 children + 8 grandchildren” multi‑stage explosion = clearing clustered enemies is the specialty of this area‑suppression grenade

Unique Effects (Mechanics)

MIRV (multi‑warhead bounce): Throw in an arc; on impact explode (100% element splash) + generate 4 child grenades. Each child lands nearby and creates 2 bounce grenades. Children explode for 25% after 2 seconds; the total 8 bounce projectiles bounce twice and explode for 25% each bounce, disappearing after the third explosion.

• In‑game: splits into MIRV and bounce grenades
• Web (Lootlemon): Throw in an arc; on impact explode, generate 4 child grenades + 100% element splash. Children land nearby and each creates 2 bounce grenades. After 2 seconds children explode for 25%. The 8 bounce projectiles bounce twice on the spot, each bounce exploding for 25%, disappearing after the third explosion
• Element roll is variable (Kinetic/Fire/Shock/Corrosive/Cryo/Radiation)
• Because of the arcing trajectory, watch for nearby walls and your own feet (self‑detonation risk)

Drop Farming

• The boss Vile Lictor of Umbral Foundry is the primary drop source (same boss as Super Soldier)
• Since it is also in the general grenade pool, it can be obtained from other sources as well

Build Compatibility

Summary

• Throw in an arc; children + grandchildren bounce and chain, a area‑suppression heavy MIRV grenade
• One throw with main 1 + 4 children + 8 grandchildren multi‑stage explosion = excels at crowd clearing
• Beware of self‑detonation with the arcing trajectory (don’t throw at your feet or too close)
• Obtained from Vile Lictor (Umbral Foundry, ≈9%)
