(adsbygoogle = window.adsbygoogle || []).push({}); From any game, CoD, counterstrike, battlefield, whatever. And link us to it unless it's so well known that youtube searching the title will immediately get us the video.
For me:
1. Counterstrike: Alive by MixEP, cheesy ass storyline but the editing is sick and the gameplay is insane for competitive counterstrike, it's a frag movie.

2. MW2: Ascendency by iReapzz and xDarkness, insane gameplay, basically it. I mean iReapzz montage 4 was also beast but the music was too screamo.

3. CoD4: Jazz - BluePrint: Killfeed rapage with some nice editing as well, the music was also pretty good and original.

4. CoD4: MuzzaFuzza and FuzzaMuzza - Balance: Nice gameplay, tons of trickshots.

5. MW2: StrummyThumbs: Creative with tons of trickshots, it seems kinda under-edited though so I don't like it as much as some others.

I know not one of these is from BO, but I just posted it in this section since its most active and I mean there's no general montages section sooo. Yeah list your favorites

Two of the best i have seen for game play and effects and timing
