Things to remember about this version:
-Elephants have been nerfed and are now wimps.
-Carp are still somewhat dangerous, but are not the killing machines they were at one point.
-Stonefall traps are almost entire useless.
-Because of the way the wound system works, no number of hammer blows will ever kill a bronze colossus.
-Spike traps can hit anyting (including your guys, so remember to turn them off) and never jam but need to be linked to a trigger.
-Magma normally does not pressurize (pressurizing can force it upwards through bends), but if it has gone through a screw pump it does, allowing for some lovely multi-z-level magma fountains.
-Enemies' habit of dodging traps can cause them to dodge of strategically placed cliffs.
-If a humanoid is dismembered (by falling extreme distances, for example), you can butcher the pieces which are not the main 'corpse'.
-A direct hit from a cave-in can kill anything (except maybe ghosts).
-Magma is the answer. Always.
I am not playing DF at the moment, but I am thinking about coming back to it at some point when the zombie invasion update is out.
