The story begins with the aliens that call themselves the Catteni, and have a much more superior way of fighting, smashing, and governing than human beings. The Catteni overpowered every military stronghold on the planet, except one. After nine months of living under dictatorship, hunger, and despair a few humans have formed an underground movement, which keeps out of Catteni sight and tries to sabotage their operations. Immersing yourself in the life of this average individual, you try to conceive how would you have felt if all that crap happened to you. This is a good thing in my opinion, because I'm getting sick of miss Croft and her two pistols with unrealistically infinite ammo supply.
Angel is different.
Since there's nobody else sane enough left on the planet, who can save the human race, your character is required to lead a team of rather cool individuals through an environment packed with unfriendly aliens. Once you've had the pleasure of meeting Angel from the nice little intro sequence, your first order of business is to get familiar with the game's options. The map screen that appears prior to every mission highlights the areas you'll need to visit. Available characters are going to be presented next to the map and each of them will have hints and tips before every mission. The main thing that needs your attention before every mission is the character equipment inventory.
