Every word looks the same. Nothing on screen tells you which one is next — the HUD names it, and you have to find it before it leaves the screen.
Shooting a wrong word scores +1 and removes something that would have killed you. Shooting the word you needed costs you, and it comes back.
Each wave the words come faster and there are more of them. Extra ship every 750 points.
The words are real. Every expansion and every explanation comes from thinQtank Learning's own acronym glossary — ninety-nine terms from Security+, CISSP, CCNA and CBROPS. The decoys are real terms too, pulled from other acronyms in the same discipline, so nothing can be worked out by which word sounds like security. Your high score is kept in this browser only.
