BUILD A MAZE OF TOWERS
Mount a defence by building hundreds of towers, choosing from the wide selection available. The placement of the towers can affect the path your enemies are likely to take across the map, so you'll need to put your strategy pants on for best results.
DEFEND AGAINST PESKY BUGS
This game contains a lot of bugs, and not only the type that the developer created with their incompetence. We're talking insects. They possess special abilities, synergize well with each other and are very angry at us for some well thought out, lore-appropriate reason.
USE ABILITIES
There are times when you need a little something extra to get you out of a pickle. Luckily, there are a variety of situational abilities ready for just such an occurrence. They allow you to disrupt the alien assault for a moment, or explode something that had the audacity to survive your clearly adequate defence.
UNIQUE MAP FEATURES
Many of the locations you fight in, as you battle your way through the campaign, have their own little thing going on that will add a bit of flavour to the otherwise completely normal experience of fighting alien bugs with plasma towers.
