As much as I'm glad that they finally fixed the achievement issue, but I'm finding myself agreeing more and more with many of the "not recommended" reviews on Steam. The developers are not being transparent about their patches (What is "general stability fix?" What are you stabilizing?), and there are other problems that haven't been addressed. The code is a mess. The Aliens' AI can't pathfind for shit, and it's hilarious watching them freeze in place and stare at you after you stumble them, making them perfect targets. I don't think Stompy was "ground-breaking AI" but even he wasn't nearly this stupid, even if he was extremely predictable. I might encounter one or two pathfinding errors during a playthrough of Isolation--the runners, bursters, spitters, prowlers, etc. will get stuck or lost countless times each mission.
Frankly, the optimist in me hopes Fireteam will greatly improve over the next several months, but the realist in me understands that possibly won't happen. I don't plan on buying another product from Cold Iron until they learn from their mistakes with Fireteam.
