Unlock All Weapons and Gadgets
You will need to complete single player story as well as co-operative story either online or local in order to unlock all the weapons and gadgets that are required for the “all weapons” and “all gadgets” achievements.
Glitch: Realistic Achievement
This is a temporary solution for a pre-existing glitch. Lets hope for future updates to provide a permanent fix. If you do not unlock the achievement for story mode completion on Realistic difficulty, go and replay the last two levels on Realistic mode and you shall be able to unlock the achievement.
Avoiding Laser Security
To do this, you need to take a human shield and go through the lasers. To your surprise, the guns won’t fire at you.
