What do I think of them ?
Rather balanced for an NX item , though I think that the Satellite Scanner should be GP only like the M32 Nade launcher.
I don't care about medkit and claymores, but Scanner and M32 Grenade launcher should be GP only.
I got Viper, Medkit and a Sat Scanner for 7 days. Impressed with the usefulness in some situations but I prefer using my default guy with Bandanna and Light Vest, you run faster than Viper. Plus you get a backpack
It's rather irritating not having 2 weapons, you can only use 1 weapon + Your special item (Claymore etc) .
That's my 2 cents .
