X-com Enforcer has a reputation of being bad. A bad shooter, a bad use of the X-com IP, and aging badly. However, for this review I will assume you've got it in the X-com Complete Pack rather than spending money on it (Please don't do that, it's not worth 5 Euro/Dollar/monopoly monies in my opinion)
As such, I will actually recommend you play it, after all, you have it from the complete pack so the only thing you can lose out on is time.

It has a lot of bad, and yes, the reputation is kind of deserved. After X-com Interceptor has you beating aliens in space, there really wasn't much else to do in the X-com story. So we're not really getting a story here.
The story is: You're a robot. You wake up. Aliens are attacking. Go kill aliens. And...That's about it. There does seem to be an idea of a story in there but it's kinda hidden.
Simple, but it works. It's slow to start, but you'll eventually unlock bigger guns, the ability to go faster than many projectiles and even more guns, and even more big guns. Did I mention you go fast and have guns? I think I did. Taken as a continuation of the X-com franchise, it fails. Hard. But if you take it as just an X-com based shooter you get as a bonus with the rest of the X-com pack it is less painful, and at times it becomes fun. After a while it becomes an amusing shooter where you slaughter entire hordes of aliens while flying from one end of the room to the other launching spinning disks with blades attached to them. There's the standard (For the time) hidden secrets to find, big levels in which you can explore a whole lot, and a lot of aliens to shoot at.
It also takes a little from bullet hell games, as your bonus points(And I think maybe super speed too) resets when you get hit. You won't die from just one quick hit, but you will find yourself actually trying to dodge things so you can keep going fast.

It doesn't make the game great. But being completely honest, I wouldn't say it's awful and bad either. Don't take it as a hardcore serious game, take it as a casual amusing shooter narrated by an amusing scientist who seems to enjoy watching his creation(You) wreck the alien invaders.
It's not good, but I wouldn't call it bad either. And since it's in the X-com pack you may as well give it a go.
At the least, play a few levels before you decide whether it sucks or not. It might surprise you

-Quick Review-
X-COM: Enforcer is a third person shooter developed by MicroProse and released in 2001. The controls can be a bit of a pain in the butt, the way you move the camera is changing the way you face, this game has a serious case of the early 2000's. It's still playable, but there are a lot of negatives about the game which will drive away most to far better games within the 3rd person shooter genre.

-Detailed breakdown review-
Oh if only I had a bit more time to finish this review, Enforcer, hello Enforcer? Can you hear me? You are trapped in my simulation and need to listen to my obnoxious voice repeat the same 4 lines of diologue throughout the whole game. Enforceeeerrr are you liiistening? Go that way Enforcer! Follow my transponder Enforcer, it's why I created it!

There ya go, you can turn off dialogue and sound now, because I basically gave you almost all recorded voice dialogue. This is a game where I was actually praying for an option to put on subtitles so I could spare myself the agony of his annoying voice.

You play as the Enforcer, basically an android-robot-thing which has been programmed for one purpose: the eradication and destruction of the alien threat. you will fight your way through the hordes of aliens, all of which are very familiar seeing as many have been seen in the previous X-COM games.

Controls:
The camera stays at an almost always fixed angel behind the main character; you cannot tilt the camera up or down, but you can turn your character. so it works. However there are a few levels where the camera is at a stupid angle where you can't see anything in front of you.

General movement was fairly straightforward, as with the previous x-com games I played them on my windows 7 laptop which has aged, but that means I played completely without a mouse, I rebinded the keys to let me strafe with Q and E, and turn with A and D. Pretty standard movement controls for most video games. The game would move most smoothly with a keyboard AND mouse though (but hey, I'm saying you can play this game with just a keyboard and a lower-end laptop!).

The rest of the controls are inconsequential: you move, you shoot, you adjust depending on your gun, you grab data chips, upgrade your character after you complete the mission, it's not rocket science most of the stuff introduced in this game is very straight forward and explains itself.

Progression:
There are a couple ways to gauge your progression through the game, the first and least effective way is to judged it based on the levels themselves... That's not very effective, since I felt like they were all bleeding into eachother.
Next you can kind of gauge how far you are into the game based on the Aliens you encounter (I keep fighting back a subconscious drive to call them "demons". Can you tell what I'm used to fighting?). This is fairly effective because you can kind of get a handle based on how far you are into the game once you start fighting bosses and regularly see larger and larger Aliens.

Lastly and the most effective way is by seeing the various upgrades you unlock throughout the game. As you progress you will find special items, when these are collected and brought back to the nerd who is constantly repeating himself in your ear, you unlock new upgrades, weapons, and power ups. As you progress you will unlock more and more of these, and this helps you get a feel for how far you are into the game. (because the empty slots mean you haven't unlocked it yet)

Conclusion:
Here's the real question Should I get the game or not?, that's very difficult to answer. If it's in your steam library you should definitively give it a shot! -- And don't give up after the first few levels. If you're considering purchasing the game I'd suggest getting getting an X-COM bundle deal.

The game's reception is very mixed, and for good reason. The game isn't even close to what the original IP stands for (which is obviously, highly detailed strategy gaming) It's not a particularly good looking third person shooter, and who likes being shouted at every 5 minutes "ENFORCER GO THAT WAY, ENFORCER GO MAKE ME A SANDWITCH".

But here's the funny thing... I really enjoyed playing this game. I don't really know what it was, but I think part of it is that I just wanted to play something different, and this game was just that; different. I played through and beat the whole game once, and after beating the game I could probably play through a second time and try to find all the secrets to unlock more weapons. (But I don't have time for that nonsense, there are more games to play and review!)

As always, thank you for reading my review, and hopefully it has been some use to you. If you have any question or comments feel free to leave them below.

The game seems strange coming from 2001 it's so jank you'd think its from pre quake days with how horrible the third person shooting feels. Sufficed to say its no fun to play and I don't see why anybody would ever bother playing this when there's so many better games in its genre.

Also doesn't help you play a robot not even a silent protagonist type... which I mean its indistinguishable gameplay wise but your creator never lets you forget your just an automaton and an extension of his will so... yeah don't bother. I read a review here saying the story and the NPCs are a lot of fun... the first one is just pure annoyance.

Do you like Gauntlet? Do you have a soft spot for the impressionistic nature of the simple geometry and low resolution textures of c. 2000 Unreal and Quake maps? Does finding letters inside of colorful balls bring back good memories of Bubble Bobble?
This is pretty playabe with a gamepad too if you remember your UT console commands from 15 years ago. Type "preferences" in the console and you'll be tapping A to bound from roof to roof of boxy trailer homes in search of the next alien spawning thingy in no time.

First of all, X-COM: Enforcer has almost nothing to do with the X-COM series aside from reusing some enemy designs and backgrounds, and even that connection is tenuous at best. So forget all notions of turn-based strategy and base building and all that. This is a simple run and gun TPS.

You run through loosely divided sections killing absolutely everything you come across -- in this case, enemies that spawn from generators. You only wield one weapon at a time and can pick up others as they spawn in the level (and they respawn after a while). Killing enemies makes them drop points (literally) which you gather and can trade in for upgrades to your weapons, health, speed etcetera. It's all kept as mindless as possible -- run around for too long without direction and you get a gentle reminder of where you're supposed to go, in the form of a big blue blinking arrow over your head, so that, in theory, even the biggest idiot can find his way around. Even so, I managed to get stuck at level 3, where you're supposed to go up somewhere but I could find no way of getting there -- the game has no mini-map or mouselook. Whether that says something about the game or me, I wouldn't care to say.

It reminded me a little of Painkiller (there's even a weapon that shoots blades), except that Painkiller has more variety, better graphics and higher difficulty. This game is by no means a classic, but as far as mindless fun goes it does what it sets out to do. I'm giving it a vague "not recommended" based on just the half hour of play I had with it. I can't really recommend buying it on its own, but as long as you don't go in expecting strategy, it's an inoffensive addition to the X-COM Complete Pack.

This game is an example of what happens when you let Hasbro get a hold of an established and popular game franchise.

It's terrible. It's link to the old XCOM games is lip service only, and the gameplay and graphics were bad even back when this was released. Really I only own it because it came with the bundle of old school XCOM games I actually wanted and it was cheaper to get the bundle than buy everything EXCEPT for this title.

If you got it in a bundle deal... congrats on being able to enjoy the other games. Don't bother installing this one unless you want to make ironic YouTube videos or have people watch your reactions on Twitch. If you are thinking of getting this single title... walk away. Just walk away and pretend this never existed. You will be glad to keep the $5.

Terrible camera, terrible animations, terrible key bindings, terrible gameplay, terrible use of the X-Com license.

is it a good xcom game? no. is it a fun game? yes. are there better games in this genre? the modern EDF games, for starters. but as part of the x-com pack, this is alright. nothing especially offensive or bad about it.

General Thoughts/Overview:

I’d heard this game was bad, but hot damn… it actively detracts from the value of the Xcom bundle.
A terrible, terrible shooter, Xcom Enforcer is quite possibly the first game I couldn’t continue to play out of sheer disgust at its awfulness… and I managed to finish deus ex: the fall.
This is an xcom themed run and gun, earn points to buy upgrades, to make you better at murdering the mass hordes.
If there is a story, I didn’t find it.

Pros:

• Easy and mindless.
  
• It was nice to see some of the iconic xcom defence maps from a shooter pov.
  
• The game is super easy to pick up and learn. There is literally no thinking at all.

Cons:

• The game is laggy and jarring and jumps around awfully.
  
• The voice acting is just painful to listen to. The whiney wheezey sounding scientist makes me hope there is a twist at the end where it turns out youre actually the alien and its some twisted experiment where a human brain has been murdering xcom agents and abducting people instead. but I doubt it’ll be anything as interesting or deep as that.
  
• The controls are awful, with no real ability to look around
  
• There is literally no connection to the xcom franchise at all. Nothing beyond skin. It’s nothing at all like any of the other games in any regard.

Suggested improvements:

• Optimise and smooth the game so it actually runs.
  
• Connect a tactical play element to the game.
  
• Tweak the difficulty settings to reflect difficulty.

Overall Recommendation:
Overall I recommend you ignore this. I played it for almost an hour and a half and it’s just bad. It isn’t even a good run and gun or arena shooter, which it was intended to be.
As I said at the start, this game actively decreases the value of the xcom bundle, this is so bad it isn’t even worth the 2 minutes of install to try out.

Negatives
_______
- No vertical camera control
- Weird camera angles throughout the game (Limited vision infront of you)
- Have to change from 'Direct3D support' to 'Software rendering' to change to widescreen resolution, and then change back to 'Direct3D support' again to be able to play in widescreen with the Direct3D (Better textures, lighting etc...).
- Automatically picks up weapons (which replaces your current weapon), can result in you getting replacing a superior weapon with an inferior one.
-/+ Voice-acting, the professor is just awkward, but the enforcer is badass.

Positives
______
+ Arcadey style action
+ Lots of alien gibs
+ Hidden secrets that unlock weapons and bonus levels
+ Good variation of weapons
+ Really fast paced action if you upgrade your speed to max (I recommend it)
