We check every store before it is listed. That check covers the seller, the checkout price, and that the store has a refund path. The refund itself follows that store's rules. We test the checkout so the price on the row matches what the store charges before tax and payment fees. Each offer shows how long ago its price last changed. Hover that time for the exact moment. The price, and whether the store still has the offer, can change after that. The list opens on the lowest price, which is the lowest offer GameGator is listing. Some Buy buttons are affiliate links, and the store may pay GameGator a commission. A region is where that key can be activated. A platform is where the game runs. A wrong price or seller can be reported to support@gamegator.net. We can correct the listing. The store handles delivery and the refund.

Shapeshifting Alien Trespassers have invaded Earth! Their vile species, known as "Third-Worlders", hails from the third planet of a nearby star system, and have now unleashed their rampaging hordes, consuming everything in their path, seeking to turn all of Earth into a dumpy Third-World Hellscape! You play as Johnny Righteous, a mild-mannered computer programmer working at the Department of Defense on a top-secret Defensive AI, known as Sentinel, before it was mysteriously cancelled. Now, using the last copy of Sentinel's code, it is up to you to turn back the tides of the invasion. Can you save civilization from the brink of collapse, and restore our High-Trust society? Or will evil Alien Shapeshifters win World War 3 by waging a Third-World War?
