Trade Secret is a 2.5D action platformer set in a post-Apocalyptic underground civilization. The game is playable in a browser and supports up to 4 players in cooperative play. Trade Secret features a unique Z-axis transition mechanic that allows players to explore levels that are beautifully rendered in 3D, while keeping the gameplay in 2D. Another innovative feature is the game’s tinkering system that allows players to craft custom armor and weapons. As members of the Sons of Salvage, players are seeking to reclaim the surface and must work their way up through the five tiers of their subterranean world. Their journey will force them into confrontations with a varied assortment of enemies – human, creature, mechanical, and hybrid, as well as diabolical traps and puzzles. Trade Secret is powered by Unity 3D to smoothly deliver exciting gameplay, hand-painted graphics and unique sounds.
