This game is well known for disappointing fans by having less features than its predecessor. But those who are new to RPG shooters may enjoy being able to use different guns freely, while upgrading your character with different special abilities (more on that later). The environments often consist of a number of different areas or zones which are linked together, and one is free to move between those areas and explores their nooks and crannies: whether they are looking to find a particular apartment and kill someone's pet greasel for a quest, or whether they are looking to find some weapons or other goodies somewhere. The story felt "pretty good," with an interesting twist or two, and there were some memorable characters therein. Once again we have a game with annoyingly short ending videos though, and I don't believe there was any "monitoring your choices" through the game, just final actions. One may love or dislike the androgynous ammo of the game: basically ammo packs of nanomachines which work for any weapon, meaning that every weapon draws on the same ammo pool. I have to admit I actually prefer this system sometimes, as in this case it eliminated some of my tendency to never use a precious rocket-launcher because its ammo was rare. With the addition of biomods which decrease ammo consumption, one can feel less and less conflicted about pulling out their rocket launcher or flamethrower, knowing that the ammo which enemies drop can be used in it all the same :D Combat was fairly enjoyable when one brings different biomods to bear, such as the "biotox drone," a hovering cloud of nanomachines which shoots nonlethal sedative darts at enemies, or the vision enhancement to spot enemies through walls. Personally I love maxing super strength as soon as I can (kill soldiers instantly by hurling dead soldiers at them XD), then you can one-hit foes with the tonfa for a nonfatal kill (police stick). There are of course many abilities to augment one's ability to be stealthy, to explore hazardous areas, and to approach situations in different ways. One can use thermal masking and bot domination to take control of enemy droids and massacre everyone with them, or one can send a small spy drone in to neutralize said bot with an emp blast. There are only three levels for each biomod, and it is fully possible to replace a bio mod you have purchase in one slot with a different one later. This means it is possible to try a different play style later in the game if one is sufficiently talented at getting their hands on biomod canisters through merchants and the nooks and crannies of the environment. This game wants you to explore, though the openness and size of its world cannot hope to compete with our modern idea of sandbox freedom. In many ways, this game is a smaller Deus Ex Human Revolution with respects the environment, the level or RPG-ness, and the impact of the story (though frankly I remember the invisible war characters better than the ones in Human Revolution... which I JUST player O_o). This is a good intro game for first-person shooter fans who are new to RPG elements. As someone who played this game and loved it, I am not sure whether I will buy it while it is on sale, because I will definitely be buying Deus Ex for the first time, which is hailed as having a much deeper RPG stat building experience and perhaps even more content. Still though... I do have enough fun memories attached to Invisible War as my into intro into the Deus Ex world.
