SteamBlaze through the world of Mainframe in this fast paced Action-Platformer inspired by the Megaman Zero Series. You play as Frame, a Data Scanner who is tasked with combating the destruction of the world. Use a variety of movement options and weapons to overcome challenges to rid the world of +ERRoR.

A Data Center known as Spectrum-016-88, a region in the norther cluster of Mainframe, has come under attack by an emerging group. Similar attacks have been levied in recent months in other Data Centers. These attacks are lead by a group who call themselves, +ERRoR. A newly founded organization known as Console has taken control of public order and safety in response to the emergence of +ERRoR. Over time public trust in Console wains as the attacks grow more frequent and destructive as +ERRoR always seems to be one step ahead of them. Despite the efforts of Oracle's Data Scanners, +ERRoR has gained more influence in a short span of time. They are now on equal footing with them and now the public has begun to question their authority as well as their actions. Within Console a growing suspicion looms–a person of great influence must be backing +ERRoR. Frame takes matters into his own hands to put a stop +ERRoR’s assault before all of Mainframe is destroyed.
Data Scanners have a wide array of movement options that allow them to move through Zones quickly.

Data Scanners have access to 2 unique movement mechanics that can be employed to get through Zones.

In addition to those movement options, Data Scanners have access to a Secondary Jump, Wall Slide, Wall Jump, Back Dash, Fast Fall, Burst Movement and a number of hidden movement options that only skilled user can make use of.
