Direct your cells and shoot everything that moves in GRIEVOUS! You will have to eliminate the bad cells and the enemies which will gravitate around you. You will have to manage to shoot the malignant cells that will rush towards your hero to hurt him. Fire as many times as necessary and quickly clear up. You will be able to choose which direction to go to explore a new room as the game progresses. Good luck to everyone and have fun! Use the arrow keys to move and the mouse to aim and shoot.
