 Gameplay 
When you start the game, you are prompted to select a map. Every map features 50 waves of increasingly difficult Vectoids (Enemies). At the start of each map, you have a small amount of Cash and 20 Lives. More Cash is obtained through killing Vectoids or through an interest mechanic, that give you Cash after each round. Cash is  used to purchase and upgrade towers. 

Vectoids are the main enemy of this game, and come in multiple colours. These colours signified the difficulty of the enemy: blue, red, green, yellow, purple, grey. However, apart from Yellow Vectoids, which move faster, the colours have no special trait, just a gradually increasing health value across tiers.

Towers share the same colour system, but only come in red,green,blue and purple. There were tiers of towers, with each colour having 3 progressively better but more costly towers, except for blue, which only has 2 tiers of towers.

The main purpose of colours is to  function like a rock-paper-scissors mechanic. Matching colours (i.e Red and Red) do more damage to enemies, certain colours would do less damage. Towers could be upgraded by using Cash upto level 10,improving their capabilities. 

Every few waves, a Yellow Token would be rewarded. Yellow tokens could be exchanged for one of 4 options: 

Placeable Range or Damage buffers, that affected nearby towers. 

Interest boosters could be aquired, modifying the interest aquired after each round.

5 additional lives
