I guarantee you'll have a laugh, for better or worse.
Deus Ex Invisible War is twenty hours of acting like a drunken lunatic in a dystopian future that is a combination of the movie American Psycho, James Bond and an Alex Jones radio program, all wrapped up in a neat bundle that'll have you spraying beer all over your monitor from laughing so hard.
Alright, so the story is decent, although nowhere near the caliber of the original Deus Ex (The games shouldn't really even share the same name, as they're completely different). It features you as Alex D, a cybernetically enhanced mercenary that is contracted by various transnational organizations and private interests to **** **** up. The missions involve burning coffee shops, murdering children and all around being the most hardcore douchebag in the world. You can throw people up like thirty feet in the air.
I should also mention that this is a very, very easy game. From the beginning right until the very end, unless you are ambushed or sorely unprepared, you will essentially dominate every adversary you encounter. There are virtually no penalties for murdering highly important characters to international security, much less for simple theft. You get the feeling that you're basically just god wandering around ****ing with people.
That being said, you will get invested in the storyline. If it is your first time playing, you may be genuinely surprised by some of the twists you encounter, and the entire story arc, does leave one feeling satisfied with the experience, albeit the conclusion itself does feel slightly truncated.
Graphics wise, this game was dated when it came out. Some of the shadows do look good though, especially the dynamic lighting. The bottom line is, if you can get this game to run, its definitely worth the five dollars it currently costs. Head over to your local bargain bin and pick this gem up, its surely worth the price of admission.
