In the Undersea Research Institute of the Cross Fire mobile game, defenders can choose the second floor of Point A and the large iron tank of Point B when guarding the point. These two points have a wide view, are easy to defend and difficult to attack, and are very safe. You need to be careful not to defend defensively, but to conduct more mobile defense.
Main weapon: repeating shotgun
Secondary weapons: shotgun + powerful secondary weapon or regular main weapon + double-barreled shotgun
Melee Weapon: Two-hit Melee Weapon
Throwing weapons: smoke bombs
Defensive ideas: Change positions more often, don’t stick to it
(1) The second floor of Package A : It is at a high place with a wide view, and it is also an unconventional location;
(2) The large iron can at Bunker B : it has a wide field of view and can cover the entire Bunker B. Moreover, lurkers must cut and jump if they want to rely on the warp. It is very safe.
The jumping method is also very simple. Just point the knife at the edge of the tunnel at point B and jump against the iron can.
