Update #8 for Titanfall is apparently just around the corner. Tomorrow, the update will go live and with it will come a "Frontier Defense" horde mode style co-op mode and a few other new features. Let's take a look at what fans can expect.
Brand new cooperative game mode - Frontier Defense

Join forces with up to three other players in this cooperative game mode to defend a vital objective from increasingly intense waves of AI combatants.

• You and your team will face down familiar foes as well as the IMC's newest combat units: hordes of Grunts and Spectres, stealthy Sniper Spectres and Cloak Drones, explosive Suicide Spectres and Nuclear Titans, ranged Mortar Titans, and even melee-resistant Arc Titans!
• Supplement your firepower by earning and deploying stationary turrets around the battlefield.
• Leverage your full arsenal against the IMC without skipping a beat by using the new Loadout Crates near the objective to switch loadouts at will, while refilling ammo and ordnance.
• Pilots who fall in battle are flown back into the fray in a dropship that circles above the action before touchdown. Experienced Pilots always maximize their impact on the struggle below by firing from the side window of the dropship on approach.
• Seasoned players can challenge themselves to beat their best score. Try to earn 3 Map Stars on each map!
• Play in every corner of the Frontier, including the maps introduced in IMC Rising and every previous Titanfall expansion!

If you would like to take a look at the full list of changes, you are more than welcome to do so.
