I had some issues.
It's not terrible. The work that went into this is evident, the damage models are nice, and i kinda liked the ability to switch off onehanding vs dual-wielding.
There's really nothing original or particularly new about this, though, it's a Doom 3 knockoff through and through - the part with the chainsaw guy in the darkness was particularly groan-inspiring. Graphics were not good, but servicable.
I had some issues with the game's tendancy to be overly cheap - on occasion it seemed impossible to avoid getting hit, and some monsters seem to take one or two hits to kill while other - the same monsters, mind you, just in different locations - required me to unload everything i had into them to make them explode.
Also, the scripting is sluggish - it detracts from the pace you're looking for when our fearless hero does a lot of standing around and staring off into space before eventually moving on.
Not particularly good, but not bad.
