Now, I know what youre going to say, "but Fluttershy, what would pushing do to add anything to this game?". simple, Youd take your shovel, and youd press the new Tertiary button (the same one used in .75 to sample colors now), and youd move the spade side ways, and give a nice shove, pushing people.
"ok that doesnt answer my question". calm your tits im getting there. This would automagically kill people if they fall down one block or more.
"now that doesnt sound very realistic" Have you ever fallen with 50 units of building materials? actually no wait, go get a back pack, stuff 50 cinderblocks into it, then drop 2 feet onto your stomach (~2/3 meters I think), youd either be dead or handicapped.
"this sounds a lot like melee, except they have to fall down a block" Oh right I forgot to mention, if they fall down a sloped surface (sloped in this case is a stair case where the steps are no more than two out from the previous step) theyll keep falling down the stares, becoming a weapon. If they hit any enemys, itll instantly kill them (the kill feed would say the person died via fatass). While melee would sound completely useless with this feature, pushing wont work on flat surfaces, itd just knock them back.
For even more realism, there is friendly pushing, because theres nothing stopping soldiers from pushing each other IRL.
EDIT:This is probably what itd look like if you were pushed down a slope
