My tfd strategy:
since everyone uses silenced weapons in TFD, they usually have thier volume turned up so they can hear those IBM Selectric typwriter guns. (m60's - i keep expecting a ding at the end of the clip)
Because of this, i use the loudest freakin gun i can find, usually the FN-Mag. Preferably something that blows the eardrums of peeps playing with thier headphones on turned way up!!
Since they crippled the OICW by making the DUD range of the nade gun sooooo far, thats out, so its the saw and fn-mag - loudest thing i can find.........Man that pisses me off, ill be standing on top of a cityblocks building and shooting down on peeps and the damn nade is a dud, at 30 feet!!! What a piece of work they made the oicw into
(i actually have stronger words/feelings about the fate of the oicw, but im a gentleman)
