Reica vs Flag in Zero Hour... you know, two of the SmileBASIC characters from Lunar Saviors and 3D Parkour lol. (The former is DLC)

ZERO HOUR TRIVIA: Defeating the final boss, Ultimate Dragon, with anyone (Flag for example) actually does something - when he is defeated, he will use my scream sample, followed with the screen going white, then black, and brings to the ending screen. This is inspired by Master Hand from the Super Smash Bros. series.

Bloodstreams Battles: Zero Hour is reaching its final stages. I still have to fix the bugs (especially the unstable menus and Corruption Dragon's flickering sprites), work some more in multiplayer (I never tested this one) and add some more things for polishing. It will also become available in SmileBASIC Source when its key becomes available, unlike BB3DS, which was released alone.

The screen in Zero Hour that you'll be met with after you activate the cheat to play BB1999.

Kakutou Game in Zero Hour's style lol.

★ Dark Flag and Cyborg Ninja, two of the hidden fighters that reside in the Pit stages ★

Showcasing what the Bizarre secret fight is. He is found at this BB3DS stage...with no music, sadly. If anyone still has BB3DS I would like to reuse the music in that stage to Zero Hour.

???

Redesigned Pit II stage in Zero Hour, likely due to my memory loss about it in BB3DS.

Copyright marking for Zero Hour, something to let it live and to avoid the same fate as BB3DS. Other than that, it's still not finished.

Dark Flag vs Flag. Likely one of the best choices for a battle, like Slicer vs Dark Slicer.

The BLOODSTREAMS BATTLES: ZERO HOUR title screen. Did you know that this screen is heavily based off the same one from Bloodstreams Battles for Nintendo 3DS (2016)?

Facing Cyborg Ninja is easier in Zero Hour, just win at the Pit and you will be sent to 3D Stage to face him. Also, you can unlock him using this method.

ZERO HOUR FACT: Press A, Y, up and left in the VS. screen to play this game. Mind me, it's the very first Bloodstreams Battles game.

A Japan-exclusive track, which plays in the Hakase's Office stage. (Yes, there's a Japanese version of Zero Hour)

Loading screen from Zero Hour. If compared with BB3DS's loading screen, Zero Hour's version is completely silent and has some animation, while BB3DS played a jingle for it and is a static image.

The game over screen of Zero Hour, a recap of Bloodstreams Battles (1999)'s game over. Only occurs on arcade mode.

Welcome back to BLOODSTREAMS BATTLES: ZERO HOUR, Sanic.

Shinko facing Imitator, who is currently morphed into Flag.

Dark Flag vs Dark Slicer - battle of Corruption Dragon's cloned allies.
