Name	Icon	Description
Broot		"On this level you'll meet the first boss. It is slow, heavy and simple, but don't think it'll be easy to deal with him, so be prepared. Destroy it and I'll report to Ensor mainframe about your success to get access to the next stage of levels and towers. I was analyzing your progress and can say that there's a big chance of success. Can't wait to see what will be opened for us next!" Slow and heavy. When HP drops under 25% it falls into rage and runs faster for a short time. When in rage, regenerates its HP with all damage taken.
Stakey		"New boss incoming! It is a representation of a blockchain, actually a chain of enemies. Data we need is stored in one first block, other blocks add layers of encryption and make it harder to crack the main block. Just try to drop those encryption layers before going for the main block. Good luck!" Can be defeated only by destroying its head. Each part of body remaining reduces the damage taken by the head.
Constructor		You will meet something interesting in this level. I think you also want to get access to a new resource? (glitch text) I don’t know, well this isn’t the interesting thing I was talking about. We need to defeat the next boss. His name is constructor, and he can make new enemies himself. Try to kill him as early as possible- when his HP drops to 75%, 50%, and 25%, he releases large groups of enemies. Very slow, becomes invulnerable and creates enemies each 5 seconds on first half of its path. Also creates groups of enemies when HP drops below 75%, 50% and 25%. Constructor is immediately invulnerable to all damage when it stops to create enemies
Mobchain		The Mobchain boss will appear in a few waves. Remember - you need different towers to cope with it. Head is invulnerable to damage during first phase. After the body parts are first destroyed, the head can then begin to take damage, but new body parts replace the destroyed ones. As with Stakey, each remaining part further reduces damage taken by the head. Phase 2 parts each have their own displayed weakness. Mobchain takes reduced damage from bullets and explosions when health drops below 66%, and then only takes normal damage from bullets and explosions after health drops below 33%. Invulnerable to all effects related to movement
