In a thread on the Respawn Entertainment forums, one Titanfall developer going under the username Scriptacus said that there’d be “no shooting through walls for this title” because designing the game to allow building decay would take a considerable amount of development.
“"It'd take a fair bit of design work to do otherwise, especially with the power of the Titan weapons,” the developer said. “From a realistic standpoint you would expect them to be the most effective at penetrating walls, but that would just make life suck for Pilots."
The developer who posted did, however, say that gamers playing this Titanfall title wouldn’t be able to shoot or destroy walls, perhaps leaving room for that gameplay element to be added in future iterations of the franchise down the road.
The game’s beta testing period is rumored to launch this week on Valentine’s Day –– you can read that full Examiner report by clicking here –– though Respawn hasn’t yet confirmed a date.
