Before creating the outstanding FPS F.E.A.R. or trying to do a good job with Matrix Online, the game developing team of Monolith Productions worked on the No One Lives Forever series (among others, of course, including Septerra Core). In No One
Lives Forever, the UNITY operative Cate Archer (basically a female James Bond spy) is fighting to free the world from the clutches of H.A.R.M. (so that's how the frightening caps spelling from F.E.A.R. came). The action-adventure game set in the '60s will engage you in 15 top secret missions along 60 levels. You'll be skydiving, fighting sharks, exploring the jungle, riding motorcycles and snowmobiles, use stealth to take the enemies by surprise and enjoy the wide variety of weapons.

Speaking about weapons, let's see what the game has, 'cause despite not bearing the real name, they are designed after real weapons.

Nevertheless, here's a list of codes to make your shooting practice easier. First you'll need to press T to bring up the talk menu.
