Sonic Forces: Speed Battle

Sonic Forces: Speed Battle is a 2017 racing game based on Sonic Forces.[1] It was developed by Sega and Hardlight for the Android and iOS mobile devices and was soft-launched on 11 September 2017 in the Philippines and on 20 September 2017 in Canada.

Development
Sonic Forces: Speed Battle was first in development in June 2016. It began as a prototype by Hardlight, checking if synchronous gameplay would work as well as they expected.

Gameplay
Sonic Forces: Speed Battle features a combination of gameplay from Sonic Dash and Sonic Rivals. Players each choose a character and race against each other online in one of many courses selected at random collecting Gold Rings and dodging obstacles as they progress to reach the goal (represented by the Phantom Ruby Prototype). Each character has different levels of Speed, Acceleration and Strength stats and has a unique selection of power-ups from Item Boxes which can be used to help the player gain an advantage.

At the end of the race, players can earn Chests which grants a range of experience points to a particular character. In addition, the first place finisher receives a Victory Chest which can be unlocked to earn larger bonuses, such as a large number of Rings or experience points for multiple characters each. Experience points and Rings can then be used to level up characters which improves their power-up Items' effects. Based on which position they finished the race in, players will then gain or lose Trophies, a numerical matchmaking ranking system akin to an Elo rating system in other competitive games. This matchmaking gameplay mechanic is part of the "Tier" system a player is at, determining which courses the player can play in and the amount of rewards the player can earn from Chests.
