Balance Changes
Damage Aura Card
Auras from different players no longer stack. Enemies standing in range will take one aura's worth of damage which will be shared between everyone.
Now +15 damage each pick, down from +20. (Added the evolution to give +5 damage each pick)
Reactor (Evolution card)
Now adds +5 aura damage per second each rank as well as the extra size, so a maxed aura damage build is as strong as before.
Tower Defence Overhaul
I have given the Tower Defence mode a complete overhaul to hopefully make the mode a more enjoyable experience for Tower Defence lovers.
Tower Defence is quite hard to balance so this mode is most likely going to receive a lot of balance updates over the near future. So if things feel a bit unbalanced with this mode, please just keep this in mind.
I'm happy to listen to feedback in the discussions thread or comments.
The Run
Everyone starts with 350 coins.
Each TD run now has 20 rounds and your towers and upgrades will stay between rounds until the boss wave has been completed.
Every 5 rounds the map changes. Everything you have built will be refunded and you will have 30 seconds to place your new defence setup.
Each kill will earn gold and a small bonus is provided at the end of each round.
Between rounds the game will now show which enemies are coming next to give an idea of what to prepare for.
Generator hit points depending of difficulty level: 20 / 15 / 10 / 10 (Easy / Normal / Hard / Nightmare).
Holding all 20 rounds pays 10 / 20 / 40 / 60 Salvage.
Enemies
Walker: The basic zombie, spawns from round 1.
Runner: Slightly faster than the walker, spawns from round 1.
Rotwing: A flying enemy type, spawns from round 3.
Sprinter: Moves faster than the runner with slightly lower HP, spawns from round 4.
The Abomination: The boss mob with a lot of HP, will spawn on wave 5, 10, 15 and 20. 2 of these will spawn on wave 15 and wave 20.
Armoured Walker: Wears a helmet and plate armour so is a little harder to kill, spawns from round 6.
Brute (Charger): Contains six zombies worth of health, spawns from round 7.
What You Can Build
Turret (100 coins)
Can only hit ground enemies.

Sky Lance (100 coins)
Can only hit flying enemies.
Best against Rotwing flocks.
Tesla Coil (175 coins)

Its arc jumps from zombie to zombie, so it is best against crowds, Runners, Sprinters and swarm rounds.

Best against large groups of ground enemies, every zombie in the blast takes full damage.
Crypt (150 coins)

Skeletons will not stop the boss, however they will attack it on passing.
