Frequently Asked Questions

Help I am stuck and can't beat a level!

Every game you play earns Coins, to progress you will need to invest these Coins in Tower Upgrades which can be found by clicking the Upgrade button on the main map screen.. These upgrades allow you to access stronger towers in levels, these towers are key to your victory in later levels!

To boost your defence be sure to use Reinforcements and Airstrikes, if you are lacking Infantry or are out of Tesla charge they can save the day!

What are the difference between the towers?

There are 4 core towers to construct in Alien Creeps TD:

Infantry - Build a barracks and the troopers inside will attempt to stop and slowdown any Creeps coming towards them.

Machine Gun - A fast firing direct damage tower, cheap to construct and fast to jump between targets.

Laser - A focused energy beam with high damage but long reload times. More effective against Shielded enemies.

Rockets - Slow firing but each Rocket packs a punch damaging any units in close proximity

Why can't I see my tower upgrade in the game?

There are 4 key towers you can place in a level, each tower has 3 upgrades and 2 abilities to unlock. These can be unlocked by purchasing upgrades via the upgrade section, then you must use the unlocked tower upgrade option to progress your towers mid action.
