Funny and very fast, some good ideas but it lacks of atmosphere.
It's very fast, more than the most of the other FPS, and that makes the action fast'n'furious.
The graphics aren't the best but not the worst either and the engine is very fast, making it running very smooth in virtually all systems. The levels are never repetitive, they are all different one from the other, although this can't be seen as a good thing from a certain point of view, as it looks more like the story was made based by the look of the levels rather than they were made to follow it. The worst thing is probably that they are very static, not much is moving (most of the time nothing at all) and that makes them look not so real.
Almost all the enemies models looks very well. Very detailed and finally with real fingers ;) and you can even see if and where they wear armour, so you can aim for the uncovered body parts to inflict more damage.
The sound is fine when talking about special effects. The music is another thing. The tracks are only short loops, and although you can finish the level before they gets annoying that doesn't mean that they don't add more to the low-budget-look of this production. Alot of things makes you feel that.
Another one is the fact that there is no introduction and basically no end sequence either. The cut-scenes are very simple. OptikNerv (the bad guy of the situation) is simply standing still or running away while talking the usual "ahahha I 0wn t3h w0rld" leet phrases. No camera change, nothing other.
The AI is not a real intelligence like in most games, but atleast the enemies here are not ONLY running at you while firing everything at hand. They also retreat, try to avoid your bullets and generally makes the fights more dinamical than most of the other games, where you can simply hide behind a wall and wait for the enemies to come at you. The fact that you can actually make the ammo supplies to explode if you fire at them add something to the action too. If you're full of ammo then you can use them to get down enemies with ease, but they also can do it... I also noticed that the difficulty level is well balanced in most situations.
Gore has a very large amount of weapons by its side, each one with more than one firing mode. They are usually very good but there are exceptions naturally.
To make levels last more, game designers often adds secrets to each level. Unfortunately Gore lacks them too. There are actually some hidden ammo/armours but I can't call those "secrets" as they are simply hidden behind a box most of the times.
I only tried the multiplayer once and I almost forgot it (I'm talking about a few years ago), but I remember some funny action.
So generally this game stands on the half-way between a good and a bad FPS, as it add some interesting things to the lot and enhances some, while lacking other ones. I must say that this game had a good potential. If you look at it you can see alot of similarities with the high scored Painkiller. Fast, non-sense action; alot of weapons all equipped with secondary fire mode; an exceptional variety of level design, all different from each other with no apparent connection between them. It only missed "that" thing that made Painkiller a success, and so this game fallen to the "common FPS bin". Perhaps that atmosphere that I was talking about in the intro, as this game's most serious lack is really that. There's nothing but the fun that makes you finish the levels and play it until the end. The "story" is so simple and boring that you'd better not read it and invent one of your own instead. It simply fails to involve you into it, giving out no real reasons to actually kill those bad dudes.
A good buy for FPS-maniacs if the price is low (I got it almost free with a magazine), but if you're looking for something that you will remember for the rest of your life then forget about it.
