Doomsday war

For kill swarms car,nothing better than a upgraded Fast Tower,better than a Heavy,cause the Heavy is slow.

at the correct position, a single heavy tower beats both 2 first waves which gives you enough money for a fast tower

A good tip is use Some simple towers at the start of the map and use some HEAVY TOWERS over the entrance.

To kill faster use the Laser Towers that are a better version than the Simple.
Use on heavy tower too,it is great if you put it into the middle with 2 Lasers in that side.

2 level 3 well positioned ice towers are a must to beat the doomsday alien boss on level 30. for level 20, tank boss v2, you just need a single level 2 or 3 ice tower to beat.

to prevent drone enemies being hasted though your defences, try setting few towers to weakest to prevent this. this doesnt work when dealing with swarm and fast only waves.
