Rhubarb Survivors: Cardio Overdrive turns your Garmin into a pocket arcade survivor — no tapping the screen mid-run. You play as a grumpy pixel rhubarb defending a garden ring from waves of bugs while the watch records a real cardio training activity named Rhubarb Survivors in Garmin Connect.

How you play
Press Start and move with your legs, not the touchscreen. Cadence and steps set how fast Rhubarb orbits the garden and how often the whip fires — faster walking or running means faster orbit and more attacks. Heart rate does not steer the character; it powers combat. When your live HR zone matches the wave’s target zone, you deal 2× damage. Short banners (for example Z3 2X HR) tell you which zone matters. Survive escalating waves, level up, pick upgrades by tilting your wrist (or up/down keys), and try not to get composted.

Enemies and waves
Aphids, worms, beetles, and boss beetles chase you around the ring. Waves advance on a timer with haptic warnings. Up to 48 enemies on screen. Earn XP, unlock whip width, acid sap, custard orbit, spore aura, fire rate, and kill regen. Hit high cadence for a Juice Storm particle burst.

Saved to Garmin Connect
Each run can save as a cardio training activity with custom Connect IQ fields: Bugs Obliterated, Highest Wave, Rhubarb Level, and HP Remaining. Heart rate and calories follow the normal activity record. View stats in the activity summary under Connect IQ / app data (store install recommended for custom fields).

Sensors
Uses the watch’s heart rate and cadence (or step-derived cadence if cadence is unavailable), plus the accelerometer for upgrade selection. Uses your profile heart-rate zones. No separate ANT+ pairing is required by the app; any HR or cadence source already working with your watch is fine.

Controls
• Select — start from menu
• Back — end run and save workout
• Cadence — orbit speed and attack rate
• HR zone match — 2× damage
• Tilt up/down (or keys) — choose upgrade during level-up

Launch tip
On many watches this appears under Activities as well as Apps → Connect IQ. Open Connect IQ and choose Rhubarb Survivors to start.
