Call of Duty: Modern Warfare is out now and features plenty of new game modes for players to try out. One such game mode is the massive 32 v 32 large-scale game mode where teams fight to capture and control certain objective points.

While the basic premise of this game mode is familiar, there is actually a hidden mechanic in Ground War that allows teams to call in a tactical nuke to end the game, but Call of Duty: Modern Warfare does not really tell players how to accomplish this feat.

How to Activate The Ground War Tactical Nuke

While Call of Duty: Modern Warfare features an updated version of the classic tactical nuke killstreak from previous Call of Duty installments, the Ground War tactical nuke is activated a bit differently. Instead of activating it by killing a large number of enemies without dying, teams can activate the tactical nuke by holding all map objectives until the DEFCON timer runs out. Once the timer is complete, the tactical nuke will deploy and end the match. This incentivises playing the map objectives instead of simply running-and-gunning the entire game.

Ground War is one of the new additions to Modern Warfare and is the largest game mode the game offers at the moment. Now that Infinity Ward has fixed Ground War player counts across several of the new maps, large teams can square off in massive battles to hold the objectives. While there will still be plenty of players running around freely or sitting in the back sniping, this game mode really focuses on players fighting for the objectives. Thankfully with the large teams, there are bound to be several cooperative team members who play the points.

While many players are currently enjoying Modern Warfare, some fans have taken to the internet to complain about certain elements of the game. Some fans are upset with Modern Warfare's maps, stating that they are too large and lean more toward camping sightlines instead of the run-and-gun gameplay the series has been known for. While this has been a minority complaint, some fans believe that Modern Warfare plays more like Battlefield or Rainbow Six Siege instead of classic Call of Duty.

Overall, Call of Duty: Modern Warfare has received great reviews from most review outlets, stating that the game is a great breath of fresh air for the series. From more in-depth gun customization to a new, more realistic approach to combat and mechanics, Modern Warfare so far seems to be exceeding expectations all around. Hopefully as the game continues to grow, Infinity Ward will continue to pump out fresh content for this hit title.
