@last Halo is in 2500 something and has aliens with plasma powered weapons and genetically enhanced super soldiers with energy shields etc.. BF:2142 is obviously in 2142 but I don't know anything else about it (:P). BO2 is in 2025 and has weapons that is actually being tested at the moment(e.g the "quad rotor") that would be added to the army in that time span or that already exist (Black birds, unmanned aircrafts etc.) that has been upgraded into robots.
