Paranoia - it is a our single-player modification for Half-life. You will play the role of a russian officer of the secret service. Your first impressions are that this mission will be just like any other, but you really have no idea what nightmares future events have in store for you...
Paranoia at it's core is a great mod. It introduced many new game features and is all around amazing. I personally thought the mod was great, but the only problem was that is was way too short. It doesn't make much sense to me why they would put some much effort into models, textures, maps, and barely use them. The mod was literally a hour long, (and I was playing on hard!) What really kinda upset me was how I thought the ending credits were the opening credits. Otherwise the game was amazing, challenging, and story-driven. I probably won't play it again any time soon, but it seems highly re-playable.
