The first being about the health system. How does it work? Is there indicators like screen turning red or is there a health bar. Also is the system Regen.

Second is why am I reading sites saying the game is released today but on the main site it says October 7th?

Thanks in advance.

1. There's auto health regen ala Halo and co.

2. Probably the European release date.

Well that is disheartening...Thanks.

There is auto health regen, but also medkits, and various health buffs and armour upgrades

I heard the hardest difficulty doesn't have health regen. Can't confirm.
