I'm very fond of the
"Conflict:" series. i own all four(on xbox): Desert Storm one and two, Vietnam, and Global Terror. Denied Ops does not count because it was a cheap attempt to tack a crap game that was only vaugely similar, on to the originals.
Many people seem to dislike these games. i believe it is because they don't understand how to properly play them. they are asquad based, third person shooters, where you are in control of a four man team, each with special skills(sniper, heavy MG, assult, demolitions, medic, squad leader). direct cotrol can be switched between each team member, and a variety of orders can be given to the whole squad, or individuals.
from the guides and walkthroughs i've seen, not many seem to grasp the versatility of four player characters. most use them only as mobile weapon platforms and pack mules. rather than setting the sniper or MG up in a good position to cover the rest of the team, they just have everyone walk together in a line. why would you bring a sniper to breech a windowless room instead of have him hang back and cover the rear? then use the MG to cover any closer areas that are out of the snipers view. the breech should only be made by the assult unit, backed by the fourth member(in DS, squad leader, in Vietnam, the medic).
ther was a similar game called
Brute Force that was in a sci fi setting.
