Mad Defense

Engineer eccentric fortification in Mad Defense, where unconventional inventors construct bizarre weaponry against monstrous siege. The castle stands as humanity's last hope, protected only by your strategic ingenuity and the engineer's increasingly unhinged creations.

Combat rewards fund continuous improvement—stronger walls, deadlier weapons, and eventually the engineer's equally brilliant brothers, each contributing unique defensive specialties. Wave escalation demands constant adaptation as enemies develop counter-strategies.

The balance between immediate survival and long-term investment creates genuine strategic tension. Will you reinforce current defenses or save for game-changing upgrades? The monsters approach regardless—choose wisely!
