"Cinematic" pauses in battle replays

This shouldn't be too hard to implement - just make the amount of time paused on a salvo proportional to the damage inflicted, and increase it further if it was a critical hit.

Start by locating the battle replay code that pauses on a salvo and read how inflicted damage and critical hits are represented. The work is done when pause duration scales with salvo damage and receives an additional increase for critical hits, with replay behavior verified.
