SOE revealed the Infiltrator today as the game's stealth-user and long-distance sniper. Using advanced technology and camouflage systems, the Infiltrator can get to places that no other class can -- and do a lot of damage once there. Interestingly enough, while the Infiltrator lacks heavy armor, SOE does claim that the class' tactical advantages will prove to be just as protective as a titanium suit.
Infiltrators can use both sniper and scout rifles as well as pistols for close-quarter combat. The sniper rifle boasts the best range, while the scout rifle is better for mobile assault missions. It will, of course, be up to the player to decide whichever is the best to use in which situation.
