I died 3 or 4 times before I decided to run like hell. I was able to get by virtually unscathed. But trust me...I didn't forget those military bastards
*This really isn't a spolier - more of a strategy*
After playing through the Agro Research level, I went back to the military outpost loaded down with upgraded weapons and armor. At the far left ( as you're facing the outpost), there is a tree over a barbed wire fence that allows you to sneak in. There is another fence that surrounds the outpost on the same side. There just so happens to be a few boxes stacked up against the fence. Climb and fire away. There are at least 20 heavily armed military dudes in the outpost.
To Darq's questions....
Are you guys in a faction? Didn't join a faction the first time, joined Freedom the second time. Will try Duty the third.
What faction and why? No particular reason for joining Freedom first. Just seemed convenient at the time.
How many of the faction missions are you doing? Most of them.
Best Weapon you have so Far? Fully upgraded 45mm P-series (the silver-looking gun, forgot the name).
Best suit? Upgraded robot-skeleton-looking thingy (forgot the name).
How many artifacts? 6
