Each of the bosses is a fusion of 3 parts: HEAD, BODY and LEGS. Each of the parts holds one unique attack type. Altogether, a bosses full body will use 3 different attacks throughout a fight.

The first three bosses you will face are pure. All 3 parts will belong to the same bug type (I.E. all three parts Hornet, all three parts Beetle). Bosses 4 and 5 are two fusions, two species in one bug hybrid. Bosses 6+ are fusions of 3 different bugs each, making each boss a 1 in 125 unique creation.

Every boss has three phases. Each phase powers up each of the bosses abilities.

After every victory you'll be graded S through F on three things:

• WEAPON ACCURACY
• DAMAGE RECIEVED
• TIME TO COMPLETE

Your post-boss scores affect your multiplier.  Good grades raise it and bad grades drop it.  If you win a boss fight, you'll regain 2 lost hearts. If you didn't take any damage you'll gain 2 more max hearts.

Your score is also your currency: everything in the shop is paid for out of your score. Buying items will deduct your score.

Your starter weapon is the pistol. Every shop will have one gun available. You can only carry one gun, so buying one from the store swaps yours out. Guns have limited ammo and reload times.

• Pistol -> 1 pellet, 12 ammo, 14 damage per shot.
• Double-Barrel Shotgun -> 8 pellets, 2 ammo, 10 damage per shot.
• Revolver -> 1 pellet, 6 ammo, 28 damage per shot.
• Bolt-Action Sniper -> 1 pellet, 1 ammo, 150 damage per shot.
• Assault Rifle -> 1 pellet, 30 ammo, 10 damage per shot.
• Semi-Automatic Sniper -> 1 pellet, 4 ammo, 40 damage per shot.
• Submachine Gun -> 1 pellet, 25 ammo, 5 damage per shot.
• Needler -> 2 pellet, 20 ammo, 8 damage per shot.

Every gun appears once before any repeats, so you'll get the opportunity for each one if you last long enough.

There are 5 species of bug in the game right now. For fusions, any part of any bug can end up paired with any other part of any bug.
