The strength of the game lies in the freedom of action during missions (several purposes etc ...).
To get from point A to point B:
- We look for ventilation and scale lines and sneaks
- We become invisible (temporarily) and we try to be discreet
- Subtlety to the devil, I put my feet and I hit everyone
In short, you liked the first Deus Ex, you love not the second, go on the 3rd!
