How to win

Roar first, fight second

Your special only works with a charged meter - sneak roars in whenever you have space, don't wait for a perfect moment.

Learn your kaiju

60+ monsters with different reach and specials - a few rounds with one creature beats randomly switching.

Don't mash

Punches and kicks trade poorly against a metered special - bait the special, then punish the recovery.

2-player is the point

Local versus on one keyboard is where this game lives - P1 takes the left side of the keys.
