Gamespots review is just plain wrong. While there are glitches this game is very entertaining.
If you liked the original Mercs, this will probably be very fun for you. While there are some glitches, well alot of glitches. Some bad AI, enemies sometimes inside rocks, one time i couldnt switch weapons for like a minute, etc. Usually they are not a big deal. I have not had any game breaking or fun stopping glitches.
This game is really creative because you will have an objective, which is basically rushing an enemy base, and you can choose whichever way you want to do it.
-snipe the whole basecamp before they realize your even around.
-run in with a machine gun and grenades.
-artillery from above and bomb the whole place to ashes.
-call a tank and blow everything with that.
-use an attack helicopter.
-c4 is very entertaining.
The only problems ive found is that alot of the airstrikes require you to be close to the target so you have to get in there and get out. Which some might find annoying, i found it fun.
The game might be pretty easy, and sometimes i wish i could change the difficulty to a more challenging choice. But there are plenty of moments where you will feel completely surrounded and die probably, or narrowly escape death. And that is hard enough to be entertaining.
