Through the next wave of patches, Far Cry 2 will be getting a feature that the community has been asking for, a hardcore mode feature. It is designed to give players a “more realistic experience”.

The hardcore setting will be available in every game mode, and have many consequences.

• A new damage model will be applied with increased damage for all weapons.
• All weapons have been rebalanced on normal mode, and on hardcore mode.
• Enemy names will disappear after the spawning invincibility period is over (a shield is displayed above a player’s head for a few second to show that he is invincible).
• A new option will allow you to tweak spawning time (but not spawning rate).
• A new search option will be available in multiplayer to allow you to find games that are playing on hardcore mode.

A release date for the hardcore mode patch was not given.
