|Allegiance||2nd Massachusetts Militia Regiment|
Simms is a fighter in the 2nd Massachusetts Militia Regiment.
Simms defends the area of Boston known as the Commons along with Weaver and a few other fighters. However as the battle wore on, both positions were lost forcing Simms to retreat. He ran into Tom Mason and his son, Hal, who were retreating from Back Bay, another district of the city, and learns that that too is lost. As Weaver informs Tom that Commander Porter has ordered a retreat and begins to start running again when a ship flies over head and drops a bomb on Southern Boston and the force from the explosion causes Simms to shield his eyes. As hysterical resistance member runs down the alley screaming the Southern Boston is lost. They quiet her before she attracts Skitters and begin to retreat towards the Militia HQ. Simms joins the 2nd Mass led by Weaver, and drives one of the vehicles along with him. Simms can be seen talking to Weaver as Matt rides his rip stick with the other kids, and when given the order to get back on the road, he enters his vehicle and drives off.
As Simms is one of Weaver's right hand men, it is assumed that he was killed in battle, as he would not have left to venture by himself.
