This update will fix the exploits and bugs that have been plaguing the FPS title. On top of that, Respawn will give Titanfall some balancing and gameplay improvements.
One famous bug that will be exterminated is with the players being stuck outside of the map boundaries. This often happens whenever the player is hanging at the back of a Titan, in an attempt to kill it, before being tossed far out of the map.
As for the balances, search drones will now be available for classic modes played on the Angel City map. Also, the damages done with the electric smoke are now more noticeable than before. Then there is the Cluster Missile which have got its damage drastically reduced against evac drop ships.
Finally is with the mega-turret. Hacking this automated weapon will now restore its health.
All in all, this is something really positive for both Titanfall and the players. Respawn have created a jewel in the gaming industry and the game developer has been taking great care of it.
