Anyone know how to get to get the security rating to a level (2).. I can't advance in the game.. Any help would be appreciated.. ThanksDeus Ex HR: security rating 2 ?
Just update your hacking augmentation to level two with a couple praxis points. You will want to level it to 5 anyways, you can get loads of experience. BTW what game are you playing, NYC? ya try Detroit!Deus Ex HR: security rating 2 ?
There are always the auto-hack devices. Any area of the game you MUST access to advance, won't be blocked by something like this. There is a password for every door and lock in the game, search bodies/boxes/objects for pocket secretaries (don't forget to read them because sometimes the passwords don't register unless you open the file.)Deus Ex HR: security rating 2 ?
You have to spend a praxis point in the hacking: capture tree (the exact name escapes me).



But there's always another way in.
