I'm down for it and have played a bit on a few of the maps. I just hate playing the ones where you get a sniper rifle. Not sure when I can get on but will do my best this long weekend I have. I've only got Eric & sixchase on my list so they'd have to find me. OB_Sic, I tried adding you but you're a popular guy.
Here's some places I think are good to hole up where throwing knives may not be as effective on the maps I've played on/or where I think would be good to try. I've played on Carbon, Bakarra, Resistance, Interchange, Dome, Hardhat, Mission, & Lockdown:
Bakarra = the building under construction along side the map connecting A & C (only 2 ways in/out with long sightlines plus a view out a third side from the second floor, would also consider the building by C that has a second floor that people snipe from facing the helicopter, also the 2nd floor building at the very far edge of the map between B/C
Resistance = the second floor cafe area overlooking C closer to the A flag or the area just underneath it and to the right (when heading from A to C and you go under the archway facing C...the alleyway tends to go back a little bit)
Carbon = near the C flag the alley like area to the right of the building if you are looking away from the B flag, the catwalk area in the middle of the map (though more open only three ways in/out with narrow lanes)
Interchange = the hollowed out building near C looking at the forklift
Seatown = the building people like to camp in that looks at A and is the corner of the map (not the tower), the building between A/C that has the ledge over the archways (the one they can climb up into with the dumpster...you can get on the ledge or this another roof area perpendicular to it)
Outpost = the bunker, or the hanger with the airplane
Lockdown = the long hallway overlooking B, the small room opposite the long hallway 2nd floor also overlooking B
Dome = the dome, the long hallway near B
Bootleg = the room between A/C near the shipping container, the room between B/C that people are always in
Hardhat = the room between the A ramp and the pipe to C
Underground = the subway tunnel underneath A
Mission = the 2nd floor of the building near A is what I have seen but no real good place on this map
I don't know of areas for Village, Downturn, & Fallen.
