Last year’s Sonic Mania was a superb return to form for one of gaming’s most enduring icons, and Sega has now delivered even more Sonic in the form of Sonic Mania Plus, which you can get as either DLC or a bundle. But before you get fanatical over the prospect of more Sonic Mania, temper your expectations: the new content isn’t all up to the same standard.
Sonic Mania plus has a couple major additions. The first involves a pair of vaguely familiar faces from an extremely obscure Japanese arcade game called Segasonic the Hedgehog: Mighty the Armadillo and Ray the Flying Squirrel. (Mighty was also in Knuckles’ Chaotix.) Like Sonic, Tails, and Knuckles, the duo comes with unique abilities: Mighty has a ground-pound that can shatter barriers and bypass certain enemy defenses like bumpers, and his shell renders him invulnerable to spikes while attacking, making some prickly levels and bosses a fair bit easier. Ray has a gliding ability that allows him to soar over long stretches of a stage. It’s a neat ability – but it’s only really useful in more open areas because using it in more cramped, hazard-laden levels like Metallic Madness and Chemical Plant can often be quite challenging.
