As one of the biggest SF series fan, I must say I didn't liked whole "SF World", but this one is better. Dark atmosphere, just like first games of the series.
Waiting forward to see what you making next.
I love cinematic effect, this adds horror atmosphere to the game.
I would love to see headshots, and blood marks on the ground ( when you shoot zombie, he starts to bleed ).
Also I want more, maybe add helicopter support or something.
"Search house" option, so you can find survivors and new items to fight with, instead of buying them from nowhere.
And last but not the least, is player model: I mean this guy on the roof, make him more visible instead of just little shadow, make gun aiming and holding visible in his hands.
Thank you for your attention. I see you was working hard on this game, and I surely will play it few more times.
I suggest you to make upgrades visible. Well, uhh for example when you upgrade health, your ship becoming bigger, when you upgrade speed additional turbines appears and such.
Otherwise, the game is good, specialy I liked the graphics. Keep it up, and make it more action.
