Okay guys, I know I haven't been playing much mods recently. I think it's because there aren't many new mods these days, not because of TF2 or anything like that.
Anyway Today I have a suitable mod for you guys. If you enjoyed
MISSION MCPOKER, which is a masterpiece, by the way, then you will like this mod too, called
Sector 6. The only downside that this mod suffers is that it's a czech mod and everything (including in game instructions) are made in czech. However, this shouldn't be a problem because we all know what 'bombe' means and players prolly won't get stuck at the part where you have to bombe the thingy to continue (I got stuck there, though, and used noclip)
Anyway take the trening[sic] level first, because it introduces you to how to fight without a suit, a skill which you will need for the first few levels of this mod.
I had no idea what the Czech intro wall of text said, but I'll make a guess. You're a member of the riot police sent to an underground scientific center to investigate an attack by terrorists from the Middle East. However your station ran out of kevlar armour for you so you have to go into battle with only your underwear and an assault rifle (ammo for which was also out of stock, your station must be on a tight budget.)
As soon as you land, the terrorists attack you. You won't have enough ammo to deal with them, so my advice is to run like a mofo to the Locked Entrance of the facility, where a badly designed transition will take you somewhere inside the scientific center.
Anyway there's a suit somewhere up ahead, but watch out for the invisible lazer that's next to the suit. Just grab it and GTFO. Make your way into the facility, and there is a terrorist guarding a crowbar and a gluon gun. I suppose those things fetch a high price on the black market, especially the crowbar. You have to take his C4 and bombe somewhere, but I have no idea where. This is where your years of Counter Strike experience come to the fore. Good luck.
So after that you do some superficial engagements with aliens and get into a vent, which will take you out to the Middle East, where terrorists are attempting to take down a Big Momma Crab. No, I don't know why, or how. Just do what you gotta do.
Anyway, walking around in the Middle East, you see your police buddies and get to the choppah. The End.
P.S. At least it's a good ending. The world is saved instead of in cripple. No one died on Xen.
