–Blood Streams–

Something similar like this other mod for Half-Life, SMod Tactical.
I have an idea that this could also be used on liquid filled barrels, water pipes, etc. Would be cool headshotting a Grunt/Scientist seeing them with blood streaming out of where you shot them. If possible, I would recommend this probably not occurring all the time when you shoot someone. Perhaps you have to shoot them in a certain spot like the neck.
–Ragdoll Features–
To add onto this subject, you will realise that in the vid I linked above shows that when you kill someone their ragdoll is stiff. Maybe BMS can have that for more realism.
–Office Complex–
The parts where you fall out of the ceiling at the office complex, do you think it would be cool to add some DMM to those? The only problem is that it can kill and be able to float down with if too light.
–Objects–
How will the objects such as boxes be like in BMS? Would you be able to push them around for cover, etc? That’s pretty much what I’m talking about. No more text needed…
