Resogun effectively plays out in 2D; however, it’s cleverly designed so that you move round each world in a loop. In this sense it’s perhaps less complicated than Super Stardust; especially considering that you can only shoot left or right, and can’t shoot at any angle you choose here.
If that sounds a little restrictive, you also have a boost that will destroy enemies as well as propelling you through the environment, a limited number of bombs that destroy pretty much everything, and an overdrive meter that can be filled by collecting green dots left behind by enemies you’ve already destroyed.
When unleashed this acts like a massive beam that quickly decimates enemies, although it only lasts for a brief time so must be timed carefully if you’re to make the most of it. -
