I have played the other 2 games in the series and this is a nice addon. The armor mechanic was a great idea, it's nice how you made different types with more health, armor and damage. However, this game wasn't without a few bugs I found.

1: The save game option didn't work for me when I did it on level 8.
2: When buying ammo, the terminal will not always give it, but it will still take your money.
3: You can buy ammo for weapons that are already at max (just needed to add that issue in incase anyone playing isn't as attentive.)
4: Just to note, the Ally A.I. is great, but I think this was the only game where he could get in the way of your shots, which can be annoying when a horde is attacking you.

All in all, decent game with some flaws, nothing that makes the game unplayable, still a nice game series, but that ending scene did disappoint me a bit after what happened throughout it.

My game does not load.

Hey, founded a bug, during pause game screen, your shield can regenerate! WTF. Also good game!

I love this game. The atmosphere, the gameplay I think it's great. Admittedly the story doesn't feel very complete. But my one chief complaint is that all walls and consoles on level 8 are invisible for me. I don't know if it's a problem on my end or in the game but it's only level 8 and it really detracts from my enjoyment of the game.

I really enjoyed the game. While playing it, I kept imagining a co-op kind of game like this with me and a friend playing. I was kind of confused when playing this game as to what was going on, character wise. As with the first game, I became increasingly frustrated with boxes, desks, etc getting in the way. It would always slow me down or get in my way, while it was great cover for my enemies, as they would PUSH a desk up to me before slipping around it.

There were a few times in the water plant level where the graphics went out. There weren't any walls displayed, but the barriers were still there. The computer terminals disappeared as well.
In the Armory level, on the left hand side where one of the key cards was, several of the little buggers would randomly come out of the floor to attack me all at once.

Despite being able to pilot a walking tank for one of the levels, I was actually kind of bored with it after the first 2 minutes. Not being able to shoot what you're aiming at, due to gun placements, was a real let down. Maybe in the future allow the guns to swivel just a little to be able to hit what the player is shooting at.

Considering that the player can simply shoot open a door with a few bullets, and ammo wasn't too hard pressed to come by, the need for keycards seemed redundant. As well, there were just too many keycards to ever need one. Also, why can't I close a door once it's open? It would have made a few areas easier to handle.

Sometimes, when buying ammo, the money would be expended, but no ammo would be added.

I was impressed with the final boss, but the final data pad I picked up left me wondering.. how is this evil corporation going to explain these other space stations failing? Are they all going to tell the families and news centers the same thing? "Sorry everyone. Wouldn't you know it? 12 more space stations had radiation leaks and no one survived." That would make them the BP of space stations.
In the end, I really enjoyed the game.
I would still love to see this game on a larger scale. If in the end it was a twin stick shoot'em up on a console platform, I think you could make it work. Just look at that "How to Survive" game for an idea. It wouldn't have to be another Outpost game.
