Pick the new ZERO slot on the Finance Tower's Day Shift character select and fight up the tower as the Dragon from Katana ZERO, a 2D pixel-art samurai in Stick It to the Stickman's 2.5D office.
What ZERO does
Slash (your attack button): cut toward the cursor (or where you face) with a short lunge. Reflects bullets back.
Roll (press down while running, like in Katana ZERO): a quick dodge roll you can't be hit during.
Chronos (special): slow time while the battery at the top of the screen lasts (about 11 seconds). The rooms go dark so ZERO and his targets stand out, and the battery recharges when it's off.
Hits go through the tower's own damage and health system, so enemies, bosses, armour and promotions all work as usual.
Plays the Katana ZERO theme while you're ZERO, with his own slash, roll and slow-mo sounds.
Your own copies
ZERO's sprites, sounds and music are read straight from your installed Katana ZERO while you play. Nothing from either game is included in the download, so you need both Stick It to the Stickman and Katana ZERO installed.
Single player. Uses your normal Stick It to the Stickman controls.
