Since then, the Xenomorphs have completely changed their tactics, and the bugs have taken the initiative to attack.

Whenever Europa tides come, the aliens will all escape from the ice, and they will attack the humans while dodging the tide's damage.

At this time, Europa's skies will become intense, with sparks and blood blooming in the sky, and humans and Xenomorphs suffering heavy casualties.

Over time, the aliens were able to withstand it, while the humans were exhausted.

"No, this situation must change, otherwise the situation will be completely controlled by the alien, and failure will become inevitable."

In the operational command, the generals frowned, and everyone felt extremely heavy pressure.

"Can the support firepower in space still be strengthened?"

Yan Chengjian shook his head: "This is already our limit. In the direction of the Royal Guard, the pressure from the alien reinforcements was increasing, and we had to send nearly three-fifths of the Battlestar over.

The asteroid ring's production capacity has reached its limit, and its output barely supports attrition on the front lines at best.

The most important thing is that building a space fortress will cost almost 10 million tons of materials, and with our current strength, we will no longer have the ability to build more fortresses, and it is extremely difficult to maintain it. ”

Zhang Binhui rubbed his temples in distress, he also felt a little poor.

The combat staff officer came over with the statistical report, because of the change in alien tactics, the expeditionary force has been able to basically grasp their breeding numbers.

"One thousand one hundred and thirty thousand, this is the latest statistics, the number of aliens has been declining for two weeks."

This is good news, indicating that the attrition on the battlefield has made the aliens feel a heavy burden, and without support and sufficient supplies, the aliens will soon be unable to support their insect tide tactics.

"It's a stalemate, and we're in a head-to-head race with the aliens, and whoever blinks first loses.

Now it's about toughness, and we must make it to the end. ”

Zhang Binhui's statement has been affirmed by everyone, but the only problem now is that the alien is a soldier for all people, and the human expeditionary force can only be maintained at about five million after many reinforcements.

Everyone is depleting, but if you replenish it, maybe the reproductive ability of the mother worm will play a winning role.

"We must find a way to kill a few female worms."

New operational ideas have been worked out. The Expeditionary Force Command unanimously agreed to change from passive to active, the movement of ground forces will be coordinated with the implementation of the new "decapitation" program, and the assassination of the Skeleton and Galaxy will be the tactical core of the next phase.

"This, this, this, and this, this is where we've had females so far, and there's not just one female worm on Europa, we need to pick out a few of these bugs."

Looking at the several positions pointed out by Zhang Binhui, Hamill scratched his big bald head: "It's not easy." Brother Xiaohui, I know that you have invincible stealth skills, sneak over and make up for them, then everything will be fine? ”

Zhang Binhui smiled bitterly: "It's easy to do it if it's so easy." I've been scouting once before, and I almost can't come back.

Adult mothers have extremely powerful senses, and they are particularly sensitive to dark matter, and I was attacked by them before I could get close to them.

How do you think I start? ”

Hamill was a little stunned: "So strong? That's really a problem. The defense of the female worm must be the tightest, and it is not easy to kill it directly, so it seems that you really have to think of a way. ”

The two groups of people stared at each other, their brows furrowed, and they didn't come up with any way for most of the day, and finally the meeting ended in depression.

At midnight, the aliens poured out of their nests again, and those red points of light completely stained the entire ice field red, and the sky and the earth were full of alien figures, and their attacks slapped on the expeditionary force's defense line like a frenzy.

Dense beams of light shot down from space, and countless insects were smashed directly to the ground as if they had been hit by meteorites.

The firepower of the ground expeditionary force was like opening a wall of fire on the ice field, the particle beams were mixed with laser rays, and swept out against the ice field, and the alien shapes that were hit were like stone seeds that were rushed away, and the stumps and broken arms flew in the air.

If you want to say that the most noisy movement is the most primitive artillery, the earthlings use these ancient firearms to the fullest.

With a "boom", the entire artillery position turned red, and those huge shells pulled out countless red lines, piercing the night sky and falling into the alien camp.

The skyrocketing sparks, flying shrapnel, and wave-like shock waves, even if they couldn't kill the aliens on the spot, they also exploded into chaos.

The alien's counterattack was furious, the same turbulent beam was unstoppable, and from time to time weapons on the side of the expeditionary force were blasted into the sky, and even half of the base support collapsed.

The firework attacks have caused great damage to the humans, and not only are they fighting back against the spaceship in space, but the slurry pillars that blast into the human camp are as powerful as lava.

Every time a beam of slurry falls, the ice sheet is always bright red. Large swathes of the positions were destroyed on the spot, and even a drop of the remaining weapons would melt down the metal structures immediately, and then the weapons would lose the ability to fight again.

"Position No. 3 is in danger, Position No. 3 is in danger, request support from headquarters, request support from headquarters."

Similar distress signals were heard endlessly, and the personnel of the space command were busy. They did everything they could to mobilize every ounce of strength, and the human defenses were in jeopardy.

In the early morning, the horizon suddenly increased a few points, and then a faint rumbling sound came.

As if thousands of horses were approaching, the ice field began to shake violently, and even the ice lumps scattered on it bounced.

As if receiving a unified order, both sides of the battle stopped at the same time, and the approaching alien escaped under the ice at high speed, and the human spaceship also landed.

The mechs and guns quickly retreated into the spaceship, and all the atmospheric ships rose into the sky, and the originally noisy battlefield suddenly fell silent.

An hour later, a wall of water with a height of more than 1,000 meters rushed over, and a curved ramp of nearly 90 degrees swept across the vast land, and then swept away along the ice field, and the "earth" that was originally full of devastation disappeared in an instant.

The rolling flood swept across Europa's ice sheet, and as the sea water under the ice sheet was completely emptied, the whole planet let out a "buzz" sound, and the ice sheet sank downward, and the flood brought by the tide suddenly became even more manic.

Once again, the power of nature forced the warring sides to stop, and the Xenomorphs had to flee back to the ice cap, which was no longer seawater, and humanity was lucky enough to escape defeat.

Everything is over for the time being, but a new battle may begin at the next moment, and the problems facing the expeditionary force are becoming more and more difficult to solve.
