The first update for CvZ’s alpha phase after its release, expanding upon Campaign, adding another 25 levels with a new challenge found within a few levels.
2 new towers to challenge foes.
-The Blowing Fan, used to shove enemies back to where they came from, but it has to sleep in between shoves. Unlocked after Campaign level 35.
-The Energy Mountain, used to demolish a field full of enemies, but it takes ages to recharge. Unlocked after Campaign level 50.
4 new enemies to challenge your defending strategies.
-The Roller Mech, it’s basically just a faster Basic Mech. First encountered on Campaign level 32.
-The Upgraded Mech, the tougher version of the Basic Mech, having 3x the health and deals 2x the damage. First encountered on Campaign level 38.
-The Gigantic Mech, a giant beast that one shots all towers that have less than 90 HP, but it moves and attacks very slowly. Also, it has 200 HP. First encountered on Campaign level 50.
-The Mech Controller, it is the same thing as a Robo-Snake KId, but can be tossed by a Gigantic Mech once the Gigantic Mech hits 100 HP. First encountered on Campaign level 50.
The new challenge adds a whole new level of difficulty. Don’t worry, it isn’t encountered too many times… yet.
Until then, wait for future updates for more towers, enemies, levels, worlds, and extra functions!

Also some small things like Electro-Shock being mostly fixed, hitboxes functioning a tad bit differently, and a new way of knowing how many levels you’ve beaten, with a star counter!
