@Sichr:
So the way surprise works (pg. 165 SR4A) is that for your surprise roll, you roll your initiative and count the number of hits. The number of hits is your "surprise score". If you've been alerted to the possibility of being surprised you get a +3 to this roll. So your init is 11 and then +3, so you rolled 14 and got 3 hits, so your initiative score is 3. Now you roll initiative, so just roll 11 dice and then this you handle normally, you add the hits to 11 and that's your initiative score.
Anyone who gets a higher surprise score than you you are unable to act against or react to for the first IP. For people without a 2nd IP, you can hold your action until the 2nd IP and then act normally against anyone.
