Sonic Robo Blast 2

Sonic Robo Blast 2 is a freeware, non-licensed game set in the universe of SEGA's Sonic the Hedgehog.

The game uses a third-person perspective and a full 3D engine. There are 3 characters to choose from: Sonic, Tails and Knuckles, each with different abilities, and their task is to go through 3 zones (Greenflower, Techno Hill and Castle Eggman), with additional unlockable levels. During the game characters find tokens that take them to special stages to get chaos emeralds or to unlock secrets. The main goal is to stop Eggman's plans for world domination. The game design and gameplay is inspired by the original Sonic games, with spin dashes, rings and power-ups that provide different shields, extra speed, invincibility, extra lives and more. There are 4 difficulty levels and additional challenges during the levels are provided through springs, floating platforms, conveyor belts, water and slime.

There is a multiplayer mode as well, with co-op, free for all, team matches, (timed) races, tag games and capture the flag. Certain weapon-based power-ups are only available in the multiplayer mode.
