Dummy Defense

Dummy Defense is a wave-defense tower game on Roblox by Mr Lazy Guy. The Noobs and Guests invaded from beyond the stars, and you are the Commander of the Dummies' counter-attack: place towers, upgrade them, and hold the line while earning cash from every point of damage you deal.

The twist is the economy. Damage itself pays, so the scoreboard is a budget — and the real progression lives between matches, where you spend Bricks on new towers, from the free starter Dummy all the way up to colossal Titan mechs. It has been in beta since October 2024, updates land almost weekly, and the difficulty climbs from friendly starter modes to the hidden Noob Experiment.

The state of the game

What makes it different

• Cash comes from damage, not kills. Every hit pays on a formula that splits between players — breaking even means staying aggressive.
• The best "towers" are the bosses. Titan mechs like the MKI Titan Dummy are single-lane monsters, limit one per player.
• Progress is horizontal. Badges unlock systems — Autoskip, the Ability shop, game speed — and two towers hide behind lobby tapes.
