A genuine late gem for the console, this vertical shoot-'em-up swaps bullet hell for a dense, demanding military approach. Mastering directional fire, managing your option pod and slipping through heavy fire call for rigor and anticipation more than raw reflexes. Harsh yet deeply fair, it has earned a flattering reputation among connoisseurs and remains a must of the genre on Dreamcast.
Complete: box, manual and disc/cart very clean. Lightly handled.

Collector interest
A vertical shooter by G.rev released in 2006, one of the very last commercial Dreamcast titles, years after the console's official discontinuation. That late date, combined with a limited Japanese run and a benchmark reputation in the genre, makes it hotly contested. Its scarcity is real rather than perceived, and demand from shmup fans loyal to the platform to the end keeps its value among the highest in the catalogue.
An underrated gem
A war helicopter, detailed scenery and a near-realistic mood: this late vertical shooter stands apart from the genre's glitz with its restraint and a clever aimable shot. Its release at the very end of the line made it obscure and sought-after. Fans of demanding shmups and careful art direction should look into it without hesitation.
Is Under Defeat still worth playing in 2026?
Released late in 2006, Under Defeat is one of the Dreamcast's last commercial shoot'em ups, made by G.rev. Its hook is piloting a helicopter whose fire tilts with your movement, demanding fine positioning and rewarding mastery. The partly modeled military art direction and the tense pacing make it a demanding, gratifying vertical shmup. Still highly prized by genre fans, it is a sought-after piece that has lost none of its edge today.
