Description

The Norbs are coming to attack your orbs and it is up to you to stop them! Build up your defences to push back the Norb advance; if your orbs are lost, you will fail! Construct your turrets to best defend against the invasion and upgrade them to provide better fire support. Watch out, though: Awesomeo, leader of the Norbs, is waiting...you had better be prepared.

FAQs

1. How do I get a higher score?

Pressing 'SPACE' will trigger the next wave early and increase your potential bonus score. This bonus, however, will only be applied if you the succeed in killing the next boss. If you lose an orb, this bonus will be lost along with it.

2. The Norbs keep destroying my orbs; what should I do?

Build a varied mix of turrets to defend yourself. Each turret has its own advantages and disadvantages, so make sure to use the turret that works best against the current wave of Norbs. You can upgrade your turrets by clicking on their bases when they are flashing, which will increase how much damage they do (and for some turrets, their range).

3. Why are my turrets not firing?

Certain Norbs are immune to some turrets. Flybos cannot be hit by big shot or beam blast turrets. Ironos are immune to ice shot and big shot turrets.
