I've been using the Game Mechanics' Initiative Cards quite successfully in my D20 campaigns for a while now, and I've decided to attempt to apply a similar concept to my new shadowrun campaign.
With the concept of quick initiative in mind, I've been designing Character Initiative Cards for my players, to help me keep track of initiative orders of effects and such. The cards are designed to be used in a sleeve protector with an erasable marker. When the players roll initiative, you write it in the top right corner, along with the # of passes they have. As they take damage, put dots in the physical and stun boxes.
Once init is rolled, order the cards in your hand, placing the End of Pass card in the back, and one by one cycle through them. When a character has acted, and she does not have any passes left, remove her card from your hand and place her down, and move to the next character. When a character has acted and they have additional passes, cycle them to the back of the hand. When the end of Pass card comes to the front, place it behind any remaining cards. Continue the process until only the end of Pass card is left, and then reroll for the next combat round. Erase the scores and write in the new ones.
I'm not sure if any additional information should go on, as mainly these are for GM use. Check out the sample page and tell me what you think.
I'm considering making a whole suite of SR4-helping cards based on the layouts of the old CCG.
