Attack Speed

You attack x% faster with weapons. Getting 100% attack speed means your weapons have their cooldown halved, making you attack double as fast.

The game uses several hidden stats to calculate the attack speed. So the results can sometimes vary. Some of those cases are:

Melee weapons' attack speed is affected by their Range. You can read about the effects on the range page.

Negative Attack speed increases the cooldown of your weapons, meaning you attack slower. However it uses a different Formular. You would expect -100% attack speed to double the cooldown of the weapon, but that is only the case for a very few weapons. Slow weapons and ranged weapons are hit harder by negative attack speed. If you have -100% attack speed, it will make your Fist Tier 4 attack 13.5% less often. While A Nuclear Launcher Tier 4 attacks about 46% less often.
There is a minimum attack speed for weapons. Going too close to this limit results in severe diminishing returns for some weapons. Fast melee weapons like Fist Tier 4 and Fist Tier 4 tier 3+ reach this amount after about 200% Attack Speed. While fast ranged weapons like SMG Tier 4, Flamethrower Tier 4, Potato Thrower Tier 4, and Minigun Tier 3 reach this point at around 100% Attack speed. Minigun Tier 4 already has diminishing returns from 0% attack speed.

Attack speed doesn't apply to turrets, or effects like Cyberball, Baby with a Beard, or Rip and Tear
