[Dmitriy_Doc]

Suggestion: add Hardcore (Nightmare) game difficulty wich will include all conditions of "Very Hard" and also:

1. During open battle player will unable to swtich weapons and armor from their backpack, switch will be able only from weapon slots which are currently equipped.

2. Same thing for grenades and inhalers.

3. Food, drinks will cause side effects if use too often (for example alchohol intoxication, Auntie's food with abnormal sugar etc.).

4. Stamina during battle (no infinite sprinting).

5. Red Zones during sub-bosses fights which will block player to ran away too far from strong unique NPC (prevent run abuse).

6. More side effects when use Light, Meduim and Heavy Armor.
