I want to ask that i noticed when im playing NS. suddeny, the icons of guns or armors, appear in bottom right of my hud. I tried it and it doen't work. then, i went back to read the guides about upgrade guns and armor to increase the next level like as Level 1, level 2 and level 3. I noticed the pic of the pistol has a SCOPE! wha??? how u do that?

As far, I don't recall being able to scope the pistol.

However, all you need to do to upgrade, is click your arms lab, and you will see 3 upgrades for both weapons and armor. Just click and watch them upgrade!

I think if your marines press use on the researching/upgrading lab it will speed up the progress.
That is something I haven't been able to test fully yet, but I've heard so.

I tried to press use on the arms lab and I'll waited too long. nothing happen. is there something that i don't get it?

and anothe thing, jon. about the pistol with scope, I found this pic from the NS maunal.
