According to the newly released PC-specific FAQs page by Activision, Call of Duty: Modern Warfare 3 will have dedicated servers (a fact we knew quite a while back), and that they will be controlled by hosts, meaning weapon progression and unlocks will not exist. On the public servers however, level progression will function normally.
Following the conductance of the interview which turned into the above mentioned FAQ page, creative director Robert Bowling stated on twitter:
“Public is about progression, private is about control.”
Does this in any way affect your decision to buy Modern Warfare 3?
