Ground Zero

You're unwilling to risk more lives and so decide to just shore up your defenses.

Another couple of months pass and a much smaller group of cyborgs arrive which confirms your ideas that they're running out of troops. One thing that's a little strange is that they don't immediately attack, they just make their presence known while attempting to stay out of the way of your snipers. They also make some "raiding" like attacks on anyone trying to leave the Fort to travel anywhere. They never directly attack the fort though.

These annoying raids go on for a year, until you get sick of them and finally decide you need to get rid of these things once and for all. You order a concentrated attack on all the cyborg raiders in the area, after a few weeks it's confirmed that they've all been eliminated. Afterwards you send a scouting force to the secret base, to see if that's the end of this cybernetic thorn in your side.

A week passes and you don't hear anything from your scouts. You curse and figure the cyborgs still have enough troops to defend their own base, but the truth is much worse as you come to find out.

A week after you sent your scout team, a new cyborg army appears within the sight of Fort Justice. Better improved looking this time too. Obviously while you were playing around with the cyborgs raiding you, someone else was upgrading and gathering more "recruits" from elsewhere while you still haven't replenished your own losses from last yearÂ…

Another battle is joined, but this time not in your favor. The fort is destroyed and in flames. Soon people are either, running, killed or captured. In the chaos of Fort Justice's final days, one of those you see captured is Marina as a big cyborg drags away her unconscious wounded body.

You desperately try to rescue her, but your head is completely incinerated by its high powered laser beam as soon as your bullets fail to penetrate its armor. Your headless carcass falls to the ground and left to burn up with the rest of Fort Justice.

Within the year, the Combine is no more and only the Cybernetic Evolution remains to continue its mission.
