...1) when you shoot a guy while he's firing and his gun noise cycles endlessly? Or the sound issues in general?
2) how the monkeys take all your armor with one silly swipe, yet armor can absorb a half-dozen bullets or more
3) the pit near the end of the last level, which is unreasonable crazy-hard unless you cheat by sticking a chair in the door and making everything come to you
4) the battle with the mutant scientist guy starts with you facing him and four soldiers, with small cover that they just toss grenades over? It's just plain bad design.
FarCry MP is pretty much a lost cause, nobody plays because it runs so badly. I got it for the single play anyways, which is the best we've had in a long time, except near the end when the difficulty is jacked up to 11. A game based on being clever and stealthy should not end with out-in-the-open gun battles which require multiple tries and luck, not smarts. Metal Gear Solid 2 suffered from the same syndrome for half of its bosses.
