I'm wondering how V's variable movement speed will affect a melee build, or if the base speed can be upgraded. As it is in the demo, V moves quite slow compared to other FPS games. And there's a gradual increase in speed from motionless to full walking. This is common in TP games but the vast majority of FP games eliminate it or drastically reduce it.
IIRC there were abilities or cybernetic upgrades that increased movement speed. There are dashes too for momentarily boosts. That and i think some upgrades like Gorilla Arm might affect the melee in some way.
