How to unlock the Block Party achievement in NBA 2K11 - Definitive Guide
This is a cumulative team trophy for one game. To block use , though to block you need to time you block just as the shooter is going for their shot. This can be difficult, so if you are having trouble then use the two controller method. In the two controller method, have player 1 be the defender and player 2 be the shooter, and then time your sequence as player 2 shoots you as player 1 blocks the shot. Do this 10 times and the trophy is yours.
This must be done in a game with at least 5 minute quarters. Sliders can be adjusted and difficulty altered. Can be done with two controllers and rules adjusted (shot clock off). This will not unlock in My Player mode.
This one may seem difficult, but since it is 10 blocks with the entire team, this achievement is actually quite simple. Using the sliders set-up from Five by Five,just keep your defense tight and as soon as they go for the shot, attempt to block it. Odds are you will swipe it away. Repeat another 9 times and this achievement is as good as yours.
