"Strategy First" has accepted design documentation for the game, so we have contacted with Yaroslav Astakhov - head of the developers
team and he has provided some details:

The size of game locations will be 200x200 meters. You cannot destroy
walls, but furniture and doors will be destroyable.

There will be multy-storey buildings

You can freely rotate camera or switch to one of several fixed positions.

The story takes place in Africa in 1990-s

Character development and combat mechanics will be exactly the same
as in original game (weapon improvement possibilities will also remain).

There's no final decision on looting yet - whether dead enemies will
retain all their equipment or not.

Character inventory will remain the same as in original game, but
will be hidden until opened, as well as character screen.

Actual work will be started in september, and release date will be
announced later.
