Dr. Robotnik is back to his old tricks, turning animals into robots, industrializing pristine environments, and generally making a mess of things. Are you a bad enough 'hog to teach him a lesson?
Sonic Axiom is a Sonic the Hedgehog fangame assembled by Vexer and released in its latest form in 2011. Its game engine is based on the fan-made Sonic Worlds engine.
Inspired by the design of the classic Sonic platformers, Sonic Axiom distinguishes itself with fantastic visual aesthetics (albeit many of those modified from pre-existing resources), impressive and diverse level design, and a huge amount of content for a fangame: Three playable characters (Sonic the Hedgehog, Miles "Tails" Prower, and Knuckles the Echidna), eighteen full-fledged levels, nine bosses, and seven original special stages, each with a Chaos Emerald you can collect or ignore.
You can download the game from here.
Have fun!
Tropes, rolling around at the speed of sound
- Alliterative Name: Like Sonic the Hedgehog CD, Sonic 3D: Flickies' Island, and Knuckles' Chaotix, the names of the levels employ alliteration, to a slightly-cheesy degree. There's Coastal Causeway Zone, Neo Night Zone, Riptide Relic Zone...
- Big Bad: Unsurprisingly, Eggman serves as the main antagonist of the game.
- Bonus Stage: The Special Stages in this game are somewhat unique in that they aren't in some 3D realm, like those of practically every official Sonic game and quite a few fangames. Instead, the player must traverse 2D platforming segments and reach a certain elevation, both within a time limit and with a prerequisite number of rings!
- Composite Character: Metal Sonic takes more from the various versions of Mecha Sonic then he does for any of his actual boss fights in Axiom.
- Dynamic Entry: Just before the fight with him, Metal Sonic bursts out from under the floor, laughs for several seconds (with an actual mouth), wags his finger, and retreats to the next room to prepare for battle.
- Evil Laugh: Right before the Final Boss, Eggman lets one out.
- Final Boss: Eggman's Humongous Mecha that resembles the EGG-HVC-001 is the last opponent of the game.
- Green Hill Zone: Essentially what Coastal Causeway Zone is.
- Hailfire Peaks: While most of the zones mostly stay within the confines of a single setting, two in particular stand out from the rest...
- Glacial Galaxy Zone is a wonderful mix of Ice Palace and Tomorrowland.
- Molten Meltdown Zone is a jamboree of Shifting Sand Land, Lethal Lava Land, and Dug Too Deep, with trace bits of Palmtree Panic and Eternal Engine.
- The boss act of Machine Mayhem is a dramatic pairing of Eternal Engine and a vast Skyscraper City.
- No Plot? No Problem!: It's never really explained what cheeses off Sonic & Co. enough to chase Eggman down this time. Who knows? Who cares?
- Oxygen Meter: Back with its usual effect in Sonic platformers. Riptide Relic Zone, the only zone containing water in significant amounts, has a monopoly on the only elemental shield in the game, which allows the player to traverse underwater without having to worry about gathering air bubbles.
- Pre-Final Boss: Metal Sonic is fought directly before the Final Boss battle against Eggman in Machine Mayhem Zone.
- Rise to the Challenge: Robotnik pulls a particularly nasty one in the boss level for Steel Station Zone. Just as you encounter him, a purplish liquid, much like the Mega Mack from Chemical Plant Zone, will start to rise. This new goop will instantly kill the player if they're ankle-deep in it.
- Super Mode: All 3 characters can go for this if you care. Gather the Chaos Emeralds and then get 50 rings...
