Automatic suicide in the StalCraft game can be a very useful tool for players of various factions. When a certain key is pressed, the macro will execute the command /suicide, which will lead to an instant suicide of the character. This is especially useful for PC players and stalker bandits, since after death a timer is hung on the character for 2 minutes, and no one from the opposite faction will be able to lift his bag. 

The key feature of this macro is that it can be useful in various situations, for example, when your character gets into a funnel or finds himself in an unforeseen situation. Quick activation of the macro will allow you to execute the /suicide command and return to your base or to another safe zone. 

It is important to note that this function carries certain risks, since after suicide your character will lose all accumulated resources. However, in some cases it can be a useful tactic, especially in PvP battles and strategic situations. Use this macro with caution and assess the risks appropriately.
