looking for a map (lockdown hdr)

i had it once...links are welcome . ty in advance

hdr? D:
You mean a lockdown with HDR? if so dm_lockdown_r3 is what you are looking for. Just download it from the website.
Go to the maps section and download the pack that has it.

i'll try that, thanks. but im sure the map was named lockdown_hdr, could'nt google it...
