If you are looking to obtain the three achievements or trophies for collecting all M-Com Stations in Battlefield: Bad Company 2 then watch both videos below (Part 1/2). These are in High Definition, they will auto play in High Definition too. If you open them in a new window, they may not. They are best viewed in 720p but 480p/360p is watchable too.
Complete Blackout Achievement for destroying all satellite uplinks. This is glitched so you will get it before getting all 24.
Communication Issues Achievement for destroying 15 satellite uplinks.
Link to the Past Achievement for destroying 1 satellite uplink.
I hope you enjoy this achievement/trophy guide. If you have any trouble, questions or anything else. Please do comment on this post or make a forum reply under this topic in my forums.
