Why Early Access?

“2 to 8 months.”

How is the full version planned to differ from the Early Access version?

What is the current state of the Early Access version?

“• 8 playable characters each with a "Unique Movement" mechanic that varies for each character (roll canceling, air dash, flight, teleport, special stances, and more)
• Universal mechanics such as Parry, Red Parry, Burst, EX Moves, Pushblock, ground and air tech rolling, and more
• Versus mode with AI or a Human using the keyboard as 2nd Player
• End-of-game statistics showing the player(s) who scored the best in 14 different categories (including most damage, most KO's, most Parries, least damage taken, most EX moves used, and more)
• Online gameplay with GGPO rollback netcode
• 20 Combo Trials for 7 of the playable characters
• Training mode of 1v1 and 2v2
• Controller support for many arcade sticks and gamepads, and there are keyboard controls”

Will the game be priced differently during and after Early Access?

“We currently are planning to not change the price after Early Access ends.”

How are you planning on involving the Community in your development process?
