Grurong Random Defense

Roll the squad. Hold the line.
Enemies march along the path and they never stop coming. You don't pick your units —
you summon them, and what you get is luck. Nine ranks, from common troopers to the rare
heavy hitters. Work with what the roll gives you, upgrade it, and hold out for 100 waves.

Features
Every summon is a gamble — nine unit ranks, and the strongest ones are rare. A lucky early roll can carry a whole run.

100 waves, 5 boss fights — bosses show up every 20 waves and put you on a timer. Clear them or the run ends.

Your units fight, you make the calls — units attack on their own. You decide when to spend, what to summon, and which unit type to upgrade.

The field fills up — kills earn resources, but let 80 enemies pile up at once and you lose. Killing fast is the whole game.

Permanent upgrades — clearing a run pays out a real pile of gold; falling short pays a little. Spend it on eight permanent upgrades: attack, attack speed, starting resources, and damage against small, medium and large enemies.

Level up your squad — gold also levels your units, but you don't choose which one. Same as summoning, the level goes to a random rank.

A run, step by step
Summon units with the money you earn from kills.

Spend bread to upgrade a unit type — every upgrade multiplies its damage.

Survive the wave. A new one starts every 40 seconds whether you're ready or not.

Beat the boss waves at 20, 40, 60, 80 and 100.

Clear the run for a real payout. Fall short and you still walk away with a little gold and experience toward your account level.
