I'm really confused with the initiative pass system in Shadowrun. For a "normal" combat situation with no augmentations or spells that increase the number of actions you can get, it looks rather easy.
On your turn, you get either a Complex action or 2 Simple Actions.
Where things get confusing is the following paragraph:
Everyone gets to act during the first Initiative Pass (in order according to their Initiative Score), characters with two actions get to go again during a second Initiative Pass, characters with three actions get a third action during a third Initiative Pass, and so on.
So additional actions give additional Initiative Passes?
When I look at the Synaptic Booster augmentation, it says:
The booster confers a bonus of +1 Reaction and + 1 Initiative Pass per point of rating.
So if I get this correctly, an Initiative Pass is "an action"? What action? Complex, Simple, Free, an Action Phase?
I would like to know if a Street Sam with IP 3 get 6 Simple actions or if I'm totally wrong in my understanding.
