Command a horde of blobs to survive the virus invasion for as long as possible. Enemy viruses will come at you in waves.

You won't be able to fight them off yourself, each blob will attack on their own. More blobs will spawn every few seconds. You can hover over each blob to see its stats including HP, attack damage, attack range, attack delay, and how many enemies they have defeated. You can also see these same stats when you hover over an enemy.

Each time you defeat an enemy, you gain experience points (EXP), which is tracked in the green bar at the top of the screen. When the bar fills up, you’ll be given three upgrade options. Click on one to select it.

Upgrades come in four rarities: COMMON, RARE, EPIC, and LEGENDARY. They can enhance your damage, HP, or the spawn rate of your blobs (how quickly they multiply). Some upgrades boost the EXP gained from defeating enemies, helping you level up faster. Others grant your blobs special abilities, like a frozen shield or the power to attack diagonally. Choose your upgrades wisely to maximize your survival.

The game runs at normal speed by default, but you can switch to 2x speed by clicking the "Play" icon in the bottom left corner of the screen.
