LOCKDOWN GLITCH TUTORIAL
I get so many pm, in which people ask me how to do this. I decided to explain, before 14th of april, when it will be patched. Sorry for my english, im still learning, im from poland. First i will give some tips:
1. Its a lot of easier to do it with rifle man, because of quick nade throw skill.
2. If you are doing it for first time, stick to door, its much easier then throwing at distance.
Many people say to aim at window, corners, etc... this is sh*t, you dont have to aim at this. The most important is time. When you do i t after first time it will be a lot of easier. Some people say to throw after 4 sirens. I do it like 0.2sec before doors open.
This may help:
