Now the people defending here can only hope that the support can arrive as soon as possible.
However, everyone is also fighting hard under the leadership of Captain America Rogers and Black Widow, relying on their remaining considerable strength to effectively fight the Ultron Robot Army.
The Science and Technology Research Center in the Mothership is located in the middle of the Mothership.
There is a wide passage in front of the Science and Technology Center, which is the only passage that can enter here.
Ultron's robot army was constantly attacking this place from this passageway.
Rogers, Black Widow, and the SHIELD guards are guarding this passage to the death …
"Another wave, everyone pay attention." After eliminating a wave of enemies, Rogers found another group of enemies coming in the passage.
The SHIELD soldiers here at the entrance of the passageway had used some metal boxes and less important equipment as cover to block the passageway.
Many Ultron Robot wreckage that had been destroyed were also used as cover and piled together with other obstacles.
A group of mechanical eyes flashing red in the passage were constantly approaching, and Rogers stared at these enemies using the cover obstacles.
They were getting closer and closer, and the SHIELD Guards, who had already experienced countless rounds of attacks, also loaded their firearms and weapons and were ready to wait for the order to fire.
"Fire!" Rogers waved his hand sharply and shouted at the same time.
M2 Heavy Machine Guns, Vulcan Gatlin, M4 Automatic Rifles, Barrett Sniper Rifles, Grenade Launchers, and other firepower poured down on the Ultron Robots in the passage.
"Da da da da da!" "Boom!
Boom! "" Buzz! "Countless firepower poured down on the Ultron Robots.
Under the intensive firepower, some of the Ultron Robots at the front were hit hard, and their armor was almost shattered, and they fell to the ground one after another.
And these were just ordinary Ultron soldiers in steel-colored armor. Their defense was weak, and they were directly turned into a pile of wreckage when they encountered powerful firepower head-on.
After the first twenty or so Ultron Robots were destroyed, the Ultron soldiers in the back with golden armor began to fight with the SHIELD Guards.
The armor of these Ultron soldiers in golden armor is not weaker than that of tanks.
"Boom!
Rumble!
Bang! Bang! Bang! Grenades and all kinds of powerful bullets hit the Ultron soldiers.
Sparks and explosions engulfed them.
Some of the robots were knocked down, but they got up again.
The first round of SHIELD's firepower was also over, and many soldiers began to urgently change ammunition for their guns.
The Ultron soldiers in the tunnel were using the powerful firepower of their equipment to attack.
The weapons and equipment of these Ultron soldiers were much stronger than those of ordinary Ultron soldiers.
Pocket missiles, continuous high-velocity plasma energy beams, energy fusion cannons, and powerful firepower were fired at the SHIELD troops defending the entrance of the passage.
"Boom!" A pocket-sized missile directly hit an M2 heavy machine gun near Rogers.
The powerful explosion destroyed the M2 heavy machine gun, and even the machine gunner was torn into pieces of charred human flesh.
Whoosh whoosh whoosh!
A plasma energy beam hit the head of a SHIELD soldier, and the head and helmet were burned through, leaving a terrible hole with a diameter of 10 centimeters.
The soldiers of the SHIELD guard force continued to suffer casualties, and the Ultron soldiers in the tunnel attacked and advanced.
These golden elite robot armors are comparable to tanks, and their firepower is powerful. This powerful attack and defense makes them far more advantageous than human troops in urban warfare and such assault operations.
However, some Super Ultron mechanical soldiers finally couldn't support and were destroyed.
After all, the SHIELD guard force is elite, and under intensive firepower, the armor of these Ultron soldiers is not invincible even if it is strong.
One by one, the Super Ultron robots in the tunnel also fell, but more of them continued to move forward and attack the tunnel defended by the SHIELD guard force with firepower.
Rogers was also forced to cover himself with a sound-absorbing steel shield, and it was difficult for him to exert his combat effectiveness in this long-range firefight. After all, close combat is the way of Captain America.
Black Widow carried a rocket launcher and aimed it at a Golden Super Ultron soldier and fired the rocket.
A powerful armor-piercing rocket pulled the trajectory and hit the heavily armored enemy.
"Boom!"
With a violent explosion, the fire fiercely illuminated the entire tunnel, the smoke dispersed, and the Super Ultron soldier turned into a charred wreckage.
"Not bad, but unfortunately there is not much ammunition left." Black Widow installed another rocket on the rocket launcher.
Black Widow fired several more rockets in succession until they were exhausted and successfully destroyed several Super Ultron soldiers.
The tunnel was covered with the wreckage of Ultron robots, but these metal soldiers did not feel tired or afraid. Instead, they sped up and rushed to the entrance of the tunnel in one fell swoop.
"Buzz …" The disc-shaped sound-absorbing steel shield with the color of the American flag flew up.
Captain America Rogers took advantage of the enemy's attack and launched his good melee.
Rogers' physical fitness, physical flexibility, and indestructible shield are enough to make these enemies lose their firepower advantage in melee.
The SHIELD troops in the research center room also focused on hitting the eyes of these golden robots with sniper rifles, or using other firearms to hit the enemies further away from Rogers.
After all, using grenade attacks can easily harm Rogers who is fighting.
After a fierce battle, these golden-armored robots were finally knocked down.
However, because of their attack, the SHIELD soldiers suffered even more casualties.
Now there are less than two hundred SHIELD guards left to defend this place.
"Huh?"
Just after Rogers breathed a sigh of relief from the battle, he suddenly found that there were still several enemies moving in the tunnel.
"It seems that this round of battle is not over yet."
Rogers grasped the sound-absorbing steel shield and became alert again, and the strengthening serum in his body was quickly restoring his physical strength.
Two more golden-armored Super Ultron mechanical soldiers rushed in from the tunnel.
But instead of shooting weapons, they held a two-meter-long golden alloy spear in their hands!
At the tip of the spear, bursts of blue plasma energy sparkled around, which was clearly a hand-to-hand weapon.
This is the fighting type among the Super Ultron soldiers. Unlike the firepower attack type, the fighting type does not rely on long-range firepower to attack the opponent, but is specifically used to engage in close combat with the opponent.
The Ultron army is mostly composed of steel-colored ordinary mechanical soldiers.
The golden Super Ultron soldiers are the elites, and the Super Ultron soldiers are divided into fighting type and long-range firepower attack type.
