First and Foremost, the game is in Early Release Alpha. But TL;DR for those of you who have already played the Original Breach and Clear and enjoyed it: get this game. It's BnC, but with zombies. I mean, really -- that is pretty awesome.
Graphics: Nothing ground breaking, but given that the original Breach and Clear was meant for portable devices, that isn't a big surprise. It still looks great for what it is, and the UI is very serviceable. The visuals certainly add to the mood, and remind me of certain areas of the urban areas of old school Resident Evil games, which is high praise in my opinion.
Audio: Music is nice and moody, and adds to the atmosphere nicely. The audio shifts when entering into tactical mode, which is a nice touch in accenting the feel from live-action to turn-based. When the music shifts, it gives a feeling of 'alright, lets do this'. Sound effects are pretty satisfying too, gunfire sounds hefty, explosions are, well, explosive. Very solid.
Gameplay: It's Breach and Clear, man. Very entertaining tactical action, especially given the circumstances. I can't say I've ever thought about approaching a zombie apocalypse with military tactics at my finger tips, but it works really well. In fact, having four well-armed militants at your disposal might seem unfair at first, but not all zombies are created equal, and you'll be surprise how quickly you can get overrun by either sheer numbers. Using your soldier's abilities (like grenades, mines, tagging enemies, and provoking the horde) goes a long way to keeping your head above water. Loot crates spread through out the stages encourage exploration, and finding ammo and medical crates when you are low really makes mowing through that horde worth the trouble. Over all, very engaging game play.
Gripes: Well, it IS alpha, so I'll try to be easy on it. Complete lack of tutorial is a bit of a pain, and there is not much in the way of VO, save for when you select your squad mates. There are bugs, of course. Getting behind cover can be a pain in the ♥♥♥, as the game doesn't like to give you that shield icon when it damn well should. Also, the squad AI needs some touching up. Sometimes, after setting up, they would shoot enemies in the very back, while three are about to eat their face. And when you are controlling a solo-guy live-action style, sometimes the squad follows you, and sometimes they don't. And the crates! Several times I had the item pop out and go right into a car, making it impossible to grab. And there are a few more things, sure, but again, this is Alpha. Most of these problems are minor, and don't stop the game from being great. Just in need of a bit of polish -- but hey! Alpha is Alpha. Overall, very solid, and I can't wait to see how much better it gets.
PS: Will update as I plow through the game. XD
