Sonic Mania

Eggman after he dispatches a group of robots called the Hard-Boiled Heavies to retrieve a mysterious energy source known as the Phantom Ruby.

The trio’s chase leads them through altered versions of familiar zones from Sonic’s earlier adventures along with entirely new environments.

As they race to stop Eggman from exploiting the ruby’s power, each hero experiences a slightly different route through the world depending on the chosen character.

Gameplay retains the momentum-based design of the original Sonic the Hedgehog titles.

Players accelerate through side-scrolling stages filled with slopes, loops, springs, and hazards while collecting rings for protection.

The goal of each act is to reach the signpost or capsule at the end while avoiding enemies and environmental traps.

Sonic can perform his classic Spin Dash and gains a new “Drop Dash” move that launches him forward immediately upon landing.

Tails can fly short distances and swim, while Knuckles glides, climbs walls, and punches through barriers, granting access to alternate paths and secrets.

Each zone consists of two acts that combine speed sections with platforming challenges and culminate in boss encounters against Eggman or one of the Hard-Boiled Heavies.

Several stages revisit and expand on areas from earlier games such as Green Hill Zone and Chemical Plant Zone, redesigned with new obstacles, alternate layouts, and updated visual effects.

Other zones are completely original, including Press Garden and Studiopolis, each introducing unique mechanics like bouncing newspapers, television projectors, or frozen terrain.

Collectible golden rings and power-ups remain central to survival.

When the player is hit, rings scatter and must be recovered before disappearing; losing all lives results in a game over.

The PAL version of Sonic Mania is currently worth €18.06 loose, versus €12.77 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
