Some of you might have already checked out the new HL2DM map by vALVE.
It is supposedly the heir of Crossfire since it features an air strike, although the layout has nothing to do with our beloved HLDM map.
RunOff, just like overwatch, lockdown or steamlab, is based on an existing map, this time a segment of the HL2 SP game were you had to get off the air boat and enter a bulding. There's no water (since they havent fixed the bug) and some things have been added, deleted, modified etc.
The map seems a bit too open. There are lots of dangerous goodies to keep the gravgun busy, but they can also give your CPU and 3D card a hard time
The air strike now features different pitch in sound to warn you of the inminent disaster, similar to the way the Cstrike bomb does.
This time, you actually get to see the missiles flying towards the gameplay area and it sure looks frightening.
Overall, a nice map, (even though it's not made from scratch) but definetely not a worthy sequel of crossfire
