Well, while powered by the 'Doom Engine,' and although there are plenty of things to shoot at here, this is also very into role-playing, besides pulling the trigger. Who cares, though? You just want to shoot at bad guys, right?
Strife won't win any awards for its plot, but it manages to be relatively engrossing, even offering a couple of neat twists and turns here and there. The hero (call him 'Strifeguy') will have to destroy said being, by attacking the so called 'Order,' mostly with the help of the resistance group known as 'The Front.' A typical alien invasion story? Yes, pretty much. This takes place in a post-apocalyptic future, after a catastrophic comet impact brought something nasty onto the planet, killing millions, and leaving a large part of the population mutated, and 'possessed' by the voice of a mysterious, malevolent creature.
