First person stealth as simple as it can be. Sneak, knock people out and use a hand full of gadgets. It works and is pretty fun.

The story is kinda Deus Ex-ish (if this is a word). You work as a special agent for an agency known as the agency.
On your third mission your target tells you something about a tracking program and you soon get suspended for asking to many questions. Later you find out, that a company called NEON is behind it. No more twists

During some intermissions, where you can explore some parts of a hand full of cities you can complete some optional tasks. They might change some things that happen a bit, but not the entire game to much.

In the end you will make some final choices and after the credits you will visit a museum where you can read what happend to some characters in the 15 years after the game events.
You can load the last section again and make different choices to see how it will change the future.

NEON STRUCT is not that long long, about four hours for one playthrough. I finished it in one session. In the main menu you can choose every level and revisit it and find every collectible.

Pick it up on sale.
