Titanfall is a single and multi-player first person shooter in a futuristic setting filled with Mech-suits and Spaceships. It is created by Respawn Entertainment, a company founded by former Infinity Ward heads Jason West and Vince Zampella.
No details have been revealed as of yet, but it appears that you are a scavenger trying to gather supplies and salvage for your fleet.
Multi-player provides traditional matches between two opposing teams. Players start the match on foot and, as they complete objective's or earn kills are eventually able to have their mech dropped into the match.
XP is earned for what you do in the match with the point value popping up on screen with each kill and objective completion.
Players on foot are not completely vulnerable to mechs as they can be armed with heavy weapons such as rocket launchers.
