But seriously, I didn't like the combat system in the demo when I tried it much.
enemies do hit hard. there is a block/parry system, which not really worth engaging with as far as I could tell in the early game. better to just attack fast to stun lock, then runaway and regen energy to engage again.
if you do get hit, yeah. its 1 or 2 shot.
gun ammo is very limited in the demo. and guns hit like wet tissues. you can do it, but its a slow whittling down largely. im sure later game ammo is more readily available.
ship battles sucked. if you get downed its auto loss. so, just let your men fight. jump across kill one/two dudes. jump back to your own boat. repeat. trying to board the other ship and fight there sucks. they respawn, and you get stuck on corners, in edges, and shit, and fighting 3v1s.
