Dead Frontier 2 is now available on Steam for no cost. At the time of this writing it was released very very recently, so there are likely to be design problems, bugs, and other issues just lying in wait to catch people unawares.
Will post more info as I spend more time on the game.
As far as performance goes, my laptop (which has no graphics card to speak of) can run it well enough (at least 30fps) with reduced resolution and the "Lowest" graphics preset. I would have went with "Potato" but that causes everything to appear the same regardless of whether the player would be shining their flashlihgt on it or not.
Anyway, Dead Frontier used to be top-down, but now they're going for a third-person over-the-shoulder perspective.
You start off with a set of damaged gear - including a gun, a piece of wood, and clothing. All of the damaged gear reduces your stats, but the pants let you carry more so you shouldn't drop those.
You don't seem to be capable of carrying huge amounts of ammo like in the original Dead Frontier games (Ammo only stacks up to thirty or so before it takes up a new inventory slot).
Zombies will sometimes get back up after seemingly dying, or may be hiding among the corpses in buildings. When in doubt, get the Stealth skill, crouch-walk up to the suspcious corpse, and hit it.
Speaking of which, when you level up, you earn a skill point used to acquire a skill. This can include things like unlocking the ability to dodge, the ability to kick, expanding your health pool, improving the speed at which you search things, and so on.
Zombies may also follow you into rooms, especially if you've fired a weapon while in the room. They won't immediately spot you if you're far away or if you're sneaking and out of their line of sight, though.
Indoors areas may have locked rooms, and keys may be found. Every so often you find places with sets of two locked doors - one with a key that can be found in an unlocked room, and one with a key found in the other locked room. The latter will always have a particularly tough zombie, which will become a searchable corpse when killed. This corpse nearly always contains a rare or better piece of equipment (maybe a good gun, a hat, etc.)
Both weapons and clothing can affect stats, including things like the odds of finding food, inventory space, headshot damage, search speed, and probably a whole lot more things.
Melee weapons have two different swings - vertical and horizontal. I can't really tell the difference between the two yet.
Guns need to be aimed for several seconds before they're accurate - shots will land anywhere within the four dots that appear when you're aiming, so you will need to take your time or you'll waste your ammo.
All in all, while the game is a bit clunky, I'm excited to see what Creaky Corpse entertainment (or whoever makes the game) does with this game.
