Gamestop has this posted on their Army of Two page now:
Important Information Regarding Your Pre-Order Weapons Code - When you first enter your code, you will receive a message saying “you have unlocked the following weapons: 1”. This message actually indicates that your code was successfully entered, not in reference to the number of weapons unlocked. Your submachine gun will be available in your primary weapons cache, but SAL-86 will be located in your “special weapons” section. Check back often to your weapons list for availability.
This is not true for me at least. I have beaten the game and the sniper is still not in my weapons list. I e-mailed them to let them know and this is what they replied with:
Dear Customer,
Thank you for contacting GameStop.com.
We apologize for any inconvenience this may have caused. From what we
have been told direct from EA, the manufacturer of Army of Two, the
code
is to unlock both weapons. The second weapon is hidden within the game
and the player must unlock certain achievements as well as finish
portions of the game before that second weapon is available. We are
still working with EA to provide us with more detail so we can further
assist our customers. Any additional information will be posted on
GameStop.com.
Best Regards,
GameStop.com Customer Service
It showed available for my brother in law right away, anyone actually have it unlock?
Gears and Beers is not a clan, it's a way of life.
