[quote name='PapiChullo']Yeah, that happens to me quite a bit. I used to try and use the sniper pack, but it's a big disadvantage most of the time. I think the radar hurts a lot too, you should be able to be "stealth" if you haven't taken a shot, unless somebody happens to stumble upon you.
But I still love this game. Pootie, I tried joining the party last night, but it gave me a connection error. I'll probably be on for a few games tonight, after the Duke game goes off if anyone wants to get a couple rounds in.[/quote]
I'm not a 100% sure how well it works, but you can get a UAV Jammer unlock. I think it hides you from enemies when their UAV is up (not really sure, haven't done any testing).
Other then that, if you use a silencer, I don't think you show up on the radar (again untested) from what I've read. It decreases the amount of damage you do though. Where as if you shoot a gun without one, you'll show up as a dot on the enemy radar.
If you like playing without the radar, once you get high enough rank I would check out Hardcore when it unlocks. It removes the hud/radar, adds in team damage, and everyone does a little more damage.
I've had connection errors too like that by the way.
