Attack speed is the number of projectiles fired from your tower.
For very low attack speeds, the attack speed value is equivalent to projectiles fired per second (before factoring in rapid fire, multishot, and bounce shot). For medium attack speeds the attack speed value is closer to bullets fired per 2 seconds and for very high attack speeds (over 40) the amount contributed per point in attack speed is further diminished.
Attack Speed has both a lab upgrade and is part of your tower’s Attack Upgrades (Workshop).
