I did enjoy the amount I played, but it gets old very quick

It's basically like that Chernobyl mission from Call of Duty 4: Modern Warfare, except better in every way. You can actually give out orders to your companion and have complete freedom over whether to attack enemies or simply sneak by them. Sure, the AI is stupid, as others have pointed out, but it's also stupid in Call of Duty. The stealth here actually works.

And the premise is surprisingly realistic. It depicts an ethnic conflict in Burundi between Hutus and Tutsis, actual real ethnic groups with actual real history of violence in an actual real country. Compared to this game, CoD4: MW looks like it was made by illiterates.

That being said, the inability to pick up other weapons makes this game extremely repetitive. Its interface, graphics (in particular bullet trails), and relatively large maps reminded me of the Delta Force series, which it kinda pales in comparison to. In Delta Force you're practically able to have the same experience as this and better, and with more variety. So, I don't think you'd be losing much by not playing it.
