Wave Defense: Trappist is a top-down tower defense game with roguelike elements where you command a mech exploring the Trappist solar system searching for rare minerals. As you construct your outpost, you must balance between defending yourself against the oncoming waves of alien enemies and extracting the planet's precious riches.
Gather resources, build your base, mine rare minerals, and unveil new mech components and weapons to gain power! Design and upgrade your mechs to fit your playstyle and make them more powerful with each run you complete. Gaining experience to unlock power-ups will let you shape each run to be unique, but only by permanently making your mech faster, harder, and stronger will you be able to conquer the Trappist system.
Control your mech and defend against the incoming waves of aliens attacking your base. Steer clear of enemies by sprinting, dashing, and jumping away, or charge towards them to blast them!
Design, build, and customize your mech by finding new modules and weapons. You can modify your mech by finding new equipment, weapons, both ranged and melee, legs for speed, or radios to call down orbital support. Add your personal touch by changing the look of your mechs, choosing your favorite colors and parts.
Gather the critical resources to build and upgrade your buildings and mechs. But you need to prioritize between resources or defense to survive the alien waves and get out with the goods.
