About the game
In Lesson Learned, players guide a character named Frank through different periods of history, in what the game frames as a distinctive spin on the tower-defense genre. Set inside an odd dreamlike world, it can be played solo or with a partner in co-op mode, tasking players with gathering resources, constructing defensive towers, and directing their own minions. The goal is to hold the line against incoming waves of enemies. MadGamesmith developed the title, which Gaming Factory published in 2024.

Buying is legal — keys come from the grey market, so a small deactivation risk exists. So before paying, check the seller's buyer protection.

The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.
