"The Titan is a dumb-fire rocket that travels in a straight line. It's designed with a very short fuse, to aid in mid-air supression, and explodes on any surface contact." In-Game Description
The Titan Launcher is a variant of the Saber Launcher providing the Doombringer with an alternative secondary weapon. Unlike the Saber, the Titan does not lock-onto or seek it's target and therefore can be fired at any time. Additionally, the Titan has a short fuse which detonates the missile mid-flight, providing a flak-like anti-air capability.
The Titan Launcher is the weapon Doombringers have been waiting for since beta. It allows you to actually make use of the class' secondary weapon slot which before this weapon was rarely employed. This was one of Doombringers main weaknesses, but no longer. The Titan provides the player with a harder-hitting option than the Chain Gun/Cannon for those times when one is needed. Like the Heavy Bolt Launcher, the Titan is useful indoors when trading shots with other heavies, although it's relatively low damage is a factor in those battles. Thanks to a rather large explosion radius, it is also useful for pushing enemy players onto your mines. One thing to remember is that the missile's range is quite limited; for example it cannot hit the conduit in the Katabatic Generator room when fired from the other side (where the two conduits are).
A calculated shot, however, can air-blast enemies and disrupt their movement, even kill them. Also, it appears that Titan Launcher's projectile hitbox is the largest of all weapons, making close-range mid-airs rather easy. This weapon can also be fired while scoped, making shots at incoming cappers (who are already coming straight at you) very easy as long as you take a second to aim properly. Thanks to the Titan Launcher, the Doombringer is now a much more fierce all-purpose class, even in Arena .
