Invasion Tactical Defense is an impressively complex Flash game where your goal is to protect a nuclear factory from an attacking alien race.
To play, you buy cannons, upgrade the factory, and deploy personnel.
Sounds simple, right?
Well, it’s not.
Thankfully, the game’s designers have added in plenty of settings to tweak and tune as you try to find the right mix, and even then it’s not an easy win, so give it a shot and see what you can do.
The world depends on it.
Caution: The site requires you to register to play, so be prepared to create an account.

One thing that makes Firefox so great is its customizability. Lifehacker has put together a nice little tutorial for changing values and tweaking the little known and littler used about:config settings. It looks daunting at first, but by following the guide, you can’t stray too far off course, and soon you’ll find yourself tweaking with ease (doesn’t that just sound illegal). Give it a try, you’ll be glad you did.
