UNDER DEFEAT

✍️ A Theory of Shmup Evolution By: Joseph Salomonsen Gradius → R‑Type → Darius → Toaplan → Cave / Treasure / G.rev 🟨 Foundations — Designed Space Gradius (Konami, 1985) The origin of control: resource systems, checkpoints, and authored space. The player shapes their ship to survive the level. R‑Type (Irem, 1987) The Force system: space becomes weaponized. A slow, methodical philosophy—positioning over reflex. Darius (Taito, 1987) Branching structure and spectacle. The first step toward non-linear shmup identity. 🟥 Line 1 — Density → Pattern → Bullet Hell (Toaplan → Cave) Twin Cobra (Toaplan, 1987) The definitive military shooter. Discipline, routing, survival. (my personal fave) Truxton / Tatsujin (Toaplan, 1988) The birth of the “Mega-Bomb” aesthetic—power as expression. Batsugun (Toaplan, 1993) The bridge to Bullet Hell. Density begins to dominate space. DoDonPachi (Cave, 1997) The system is complete. Patterns become language. Mushihimesama (Cave, 2004) The organic extreme. Bullets form ecosystems, not just obstacles. Deathsmiles (Cave, 2007) A divergence: horizontal design fused with atmosphere. Bullet hell becomes mood, not just system. 🟩 Line 2 — Weight → Realism → Physicality (Seibu → G.rev) Raiden II / DX (Seibu, 1993) The peak of “Heavy Metal” sprite-work. Industrial, grounded, uncompromising. Under Defeat (G.rev, 2005) The final expression of the military shmup. Momentum, recoil, and battlefield physics replace abstraction. Here: space > bullets weight > pattern movement > memorization 🟦 Line 3 — Mechanics → Abstraction → Philosophy (Iuchi Lineage) Hiroshi Iuchi ❤️ Radiant Silvergun → Judgment Silversword → Ikaruga → Kokuga → Ubusuna Treasure → M‑KAI → G.rev → M2 Radiant Silvergun (Treasure, 1998) The maximalist foundation. A shmup with layered systems and narrative ambition rarely seen in arcades. Judgment Silversword (M‑KAI, 2004) The technical bridge. The “Silver” philosophy reduced to pure system and code. Ikaruga (Treasure, 2001) The minimalist apex. Seven weapons collapse into one binary system: Black or White. The “chess” of shmups. Kokuga (G.rev, 2012) The tactical pivot. The ship becomes a tank. Weight replaces speed. Strategy replaces reaction. Ubusuna (M2, 2025/2026) The philosophical return. A synthesis of polarity and modern standards—a reflection on the lineage itself. ✅ Synthesis Shmups do not evolve in a single line. They fragment into three competing philosophies: Toaplan → Cave = density / pattern / abstraction of space Seibu → G.rev = weight / realism / physical presence Treasure → Iuchi = system / reduction / philosophy All of them emerge from: Gradius = designed systems R‑Type = controlled space Darius = structural possibility ✅ Final statement From Gradius’ authored space to Cave’s infinite bullet fields, from Iuchi’s compression of systems to G.rev’s return to physicality— The shmup is not just reflex, but a philosophy of dynamic control.

Beğendim.

Solid shooter. Once the controls become obvious, it becomes a treat.

An absolutely amazing shmup. Although simple in scoring, controlling your copter in order to adjust it’s shooting angle paired with the cooldown “option” (mini ship that helps shoot) creates a very satisfying muscle memory loop. One part shmup one part rail shooter, stages feel very satisfying blowing up all the enemies/environmental effects and boss battles have a distinct, epic charm. I highly recommend this title

Ultra boring. Uh wow! This one uber barker got offended enough to say something that breaks Steam terms of use. I'll be gentle on ya this time. I'm really glad if you own this title and think it is manna from heaven. I definitely noticed the atrocity of obvious German nazi WW2 axis uniforms cosplay. That part makes me feel very uncomfortable to play this title. I was drawn in by the fact it was a NAOMI hardware title I did not get a chance to play. I was super excited when I purchased Under Defeat on 50% off sale. Unfortunately, I did not get the Twin Eagle feels, not even the Scramble Spirit feels. It just seems like old SHMUP mechanics got a polish and now you can make your copter turn around. Sort of. It looks great, and wish you a great Under Defeat gaming experience. After checking out Under Defeat, I got a refund. The NAOMI hardware was awesome..

ABOVE VICTORY
