Under normal circumstances, a knife would not be able to take down a building. It would be a mismatch. Like Barney vs Godzilla. But anything can happen in video games. Especially when there are glitches involved.
The particular glitch we are drawing your attention to here takes place in the recently released and considerably awesome Battlefield Bad Company 2. It would seem that this particular building on the Isla Inocentes map is prone to exploding itself if anyone so much as looks at it. Or at least stabs it in the right place with a knife. Have a look:
It also reduces itself to rubble in dramatic clouds of dust when shot in the same place. Talk about a touchy erection.
There is some discussion as to whether or not this is fake or real. We think it's real. We should - in the name of gams jarnalism - check it out, but frankly we've got a lot on this morning and don't have the time. If anyone can confirm this bug actually really happens in the game, feel free to let us and everyone else know in the comments. Cheers.
