Watched a video on this game, wanted to leave my two cents as a viewer as I think this game has a lot of potential. First of all, I'm fairly certain the droid guiding you has an ai voice, a little jarring, but I think it should be changed if possible. Secondly, I think this game would benefit from being first person for immersion honestly, and the initial cutscene that introduces the zombies would be better if you had more control when meeting them and were able to see them rise up for yourself. The droid being worried about itself dying doesn't really hold any weight as we have no time to really bond with it and it doesn't really make sense for a droid to say. If you wanted to kill it off, it would be better if it was as you progressed and it slowly warned you that it was shutting down until you were alone. In the Star Destroyer portion, you would be better off utilising dimmer lighting and less cutscenes and making the zombies less "COD like". Just having them walk at you makes them not scary. If you were attempting to find ship logs, or some other objective without knowing where they were or when they were coming, it would be a lot more threatening because you would be constantly on edge until you first see them, then, you can begin to have them come for you, attracted by the gunfire. Helplessly trying to hold off Vader at the end would be pretty cool.
As for nitpicky stuff, I think the blasters should have the names of their actual models, rather than standard "Assault Rifle" classifications. The fact you land in a tie fighter with a series security droid doesn't seem right personally, so perhaps being a lone survivor of a squad piloting a Lambda Class Shuttle would be more appropriate. The part where your droid tunes into a "Radio broadcast" is quite funny as it is clearly not set in universe. Also, the reloading of the blasters seems inaccurate. I believe it should be based on heat rather than ammo for both portions, not just in the Star Destroyer. I know this was only done to make the survival easier though. The random cutscenes showing zombies are very jarring as they last too long and don't really accomplish anything. Honestly, cutscenes are too frequent in general. Also, during gameplay the blaster bolts don't seem to come from the actual?
I apologise for writing so much, I know you'd have a lot to read already and I know my opinion is less valuable as I haven't played, but my laptop isn't built for stuff like this. Regardless I hope my feedback is useful.
