You are a virgin T-cell moving through the body towards the lymph node where the B-cells hang out. Those guys produce antibodies which opsonize bacteria making it more "tasty" to phagocytes (Macrophages, neutrophils etc.) so that they can kill them more easily. WASD or Arrow Keys to move. Don't touch stomach acid or acid coated spikes.
