- Turrets goes on to the next angle based on a counter. The counter then gets a new value, and this repeats forever.
- The counter is set to between 32 to 255 frames. It gets a random number 0-255, and if it's lower than 32 it sets it to 32. So 32 is the most common value, but it's still uncommon overall.
- The same goes for the shots. But the range here is 128-255 frames. Code works the same, so half the time it will be exactly 128 frames, and the other half it can be anything 129-255.
