Just bought this! Any tips? Played the beta a bit but only played terrorist hunt. Not PVP, which I am going to play now.
Find yourself a teammate that communicates well by mic.
Have a good headset.
Don't spot with the camera unless you have too, because they will notice it and most likely shoot the camera down, denying any more information on their location. (You can use the spot to your advantage by making them turn around to find the camera and having a teammate flank them.)
Don't use fuze with the hostage! The hostage doesn't like having too many balls around them.
Once you know the objective point, hide your camera, either another floor or room because you'll be able to use it again. (Yes you do have a second one) Don't throw the second one if the first one is still alive, because the first one will disappear.
Take it slow, it's not COD!
Aim for the head, its OHK.
Check your corners.
You can plant a bomb difuser next to a window and defend it from a window rappeled upside down.
Use the 5 second undetected to your advantage to get out of the area and flank enemies outside! (For example, in Hereford base, leave from the 2nd lvl staircase, drop to ground level walk into the enemies breach entrance and triple-kill them with a shotgun.)
If you play as Thermite and you see that the wall is electrocuted, use your frag grenade and roll it into the room if you see a hole for drones. (Helped me out on that one mine shaft)
