Battlezone: Rise of the Black Dogs is completed. This game was a very nice surprise to me. When I first looked at the negative reviews about this game and its difficulty rating on gamefaqs.com (Unforgiving), I was already demotivated. Then, I told myself that I would be able to complete it, even if it would take a lot of time. When I started playing it, I was very happy to see that the game isn't that bad. In fact, I liked it a lot ! The controls are good, it is not a terrible game visually and above all, I really liked the concept. I would classify it as "StarCraft in 3D". The missions, while not very diverse, were fun and not difficult at all. I don't know why this game is considered to be so hard.
I completed the Arcade Mode first with the three teams (American, Soviet, Black Dog) to be prepared for the mission-based Pilot Mode. I completed this second mode with the Americans and I really liked the story in it. I won't spoil anything, but there's something I really liked in the progress of the story. Message me if you're curious ! I would definitely recommend Battlezone: Rise of the Black Dogs if you like strategy games. It is not a game for everyone, but the fact that it's so unknown is astonishing. If you see it for a low price, go for it.
Underrated game.
