===Opposed Rolls===
;Opposed Roll:An opposed roll is any action in which there are two or more participants, and one party is actively resisting the efforts of the other. Examples include one character trying to shoot another, two hackers fighting each other for control of a system, or a police officer trying to run down a fugative. In all Opposed rolls, there is an Actor and a Reactor. In the case of combat, the Actor is the one making an attack, and the Reactor is the one defending. Other situations may not be so clear as to who is Actor and who is Reactor, but follow this rule of thumb: Whoever initiated the event or action which requires dice to be rolled is assumed to be the Actor, and whoever must use a roll in an attempt to stop the action is considered the Reactor. Opposed rolls come in two varieties: Simple and Complex.
;Simple Opposed Roll:This is for situations where speed of game play is preferred over added detail, and is what will be used most often in combat (with a few exceptions, noted in the combat rules section). After the Actor makes their roll as per an Unopposed Roll, following which the Reactor must then make their own roll against their chosen skill. Whichever player comes closest to their Target without going over wins the contest.
  
Example: Bob is attempting to punch Dave in a fist fight. Bob’s Target is 49, and Dave’s is 34. Bob rolls his dice and comes up with 39. Since Bob’s initial check succeeded, Dave must now roll against his Target of 34, and comes up with 30. Since Bob is 10 away from his target and Dave is only 4 away, Dave wins the contest.
;Complex Opposed Rolls:Initially making a complex opposed roll is identical to a simple opposed roll. The Actor makes a percentile roll and attempts to roll under their TN to succeed. However, once the Actor does roll under their target, things work differently. The Result of the roll is then passed onto the Reactor. *Their* goal is now to not only roll *under* their *own* TN, but also to roll *higher* than the result of the first roll! 
 
Example: Bob is trying to shoot Dan. Bob’s TN is 56 and he rolls a 33. Dan must now roll against his TN of 45 as well as the result of 33. In order to successfully dodge (and cause Bob to fail), Dan must roll lower than 45, and higher than 33.
