Gunstar Heroes enters the SEGA Forever collection of classic games, play it for free
Due to the fact that it runs in an emulator, it's pretty obvious that optimization needs a lot of work, something that SEGA didn't seem to bother to fix before launching a game.
You'll be burning enemies using flame-throwers or blow them up to smithereens with homing missiles. Gunstar Heroes features local, cross-platform multiplayer over local Wi-Fi, so Android and iOS users can play each other.
The game is available for free, but it's ad-supported, so you'll have to pay $1.99 if you want to remove them. Furthermore, haptic and controller support is included as well, along with the option to save your progress.
