Now, I'm no scientist. Or console engineer. I don't know how this is happening. All I know is, there are increasing numbers of people playing Modern Warfare 2 on 360 saying the game's ammo counters are all busted up.
Essentially, people are joining MP matches, then finding that there are no ammo counters. It's unlimited ammo. On all weapons. Here's one forum post highlighting the issue, but hit the internet, you'll find dozens more. And some videos. Like these ones.
Like I said, I don't know how this is happening, but word on the street is that it's an exploit - created by modders - that can be "passed" around, like a virus. Only, instead of corrupting data, it blows up MW2 maps.
I'd post more videos, but it seems every single one has awful cheese-metal/pop-rap playing over the top, so I'll spare you the torment. These ones should suffice for now.
Soon as we hear from Activision - or find out how extensive this glitch is, or how it's happening - we'll update you. In the meantime, any of you guys run into this? If so, fire off in the comments section, let us know how it went down.
