Yes, Raiden IV is not a typical shmup by contemporary standards, and won't be for everyone. Equally, all of these modes have been available in some form elsewhere. But as a single package, Raiden IV x Mikado Remix offers the Switch one of its best shooting game releases yet – and that is saying something on a console that has emerged as an unexpected star vehicle for the genre.
R-Type Final 2 makes an authentic if flawed contribution to an iconic shooting game series. Many of the problems seem technical, so hopefully an update could do plenty - especially if it lets you lock that camera pitch. All we can hope for, then, is that we are still in the beginning of R-Type's final phase, and that what Final 2 gets right is allowed to rise to the top.
Overall, Capcom Arcade Stadium is a very good package filled with brilliant games, each updated with modern functionality. It doesn't rival the quality of original hardware or the likes of M2's sublime individual ports of arcade masterworks as seen with the release of Esp.Ra.De Psi, but at £30 for 32 games, it is well worth the price, warts and all.
Rival Megagun may fall short of the standards set by genre masterworks like Cave's Ketsui, Seibu Kaihatsu's Raiden Fighters Jet or Raizing's Battle Garegga. But those are some of the finest pieces of game design of all time, and failing to meet their lofty standards doesn't stop Spacewave's creation being a tremendously fun and rather distinct shmup that really does offer something fresh, and serves as a great demonstration of the Switch's multiplayer prowess in the process.
