I've been addicted to Starfarer (Starfarer) for the last four months now. It's a killer indie space combat game.
It's a top-down 2D space combat sim, where you fly all kinds of ships ranging from small tramp freighters like the Hound to massive flying fortresses like the Onslaught or Paragon-class capital ships.
Ships are customizable, and the combat (especially when using ballistic weapons) has real heft and weight to it, with armor plates buckling and heating up, systems getting temporarily knocked out, and blinding explosions. You also act as an admiral and give general orders to your fleet, which the AI carries out.
Speaking of which, the AI is surprisingly (and sometimes maddeningly) good in this game. Fighters will dance out of weapon range, dodge missiles, and flee if things turn bad. Ships can be ordered to escort you, harass enemy ships, engage fleets, strike one ship, or provide fire support.
It's got pretty solid levels of customization; each ship can have its weapon loadouts swapped in and out, and add hull modifications to boost speed, shield strength, ammo levels, weapon range, or any number of other useful traits.
It's still in alpha, but there are both challenging missions and a fairly in-depth sandbox campaign that lets you start out small and work your way up to a massive fleet by capturing and buying new ships.
It's also very easy to mod; so easy, in fact, that using a few community-built tools, I've added in my own custom ships. People have added weapons, factions, and even entire new star systems.
The learning curve is a little steep when just starting out, but the tutorials and manual will give you the basics. Feel free to ask me if you pick it up and get confused, lost, or stuck.
I've gotten hundreds of hours out of it so far, and it's only $10. Seriously. Check it out.
From you're description this sounds like space pirates and zombies. I can't see the pics because its throwing up an error but does that soundlike a fair comparison? Because that game owns.
this sounds like a cool thing to check out I think I'll download it tomorrow!
