[3-1] The story so far...

Get the lowdown on Quake's backstory and your mission objectives. Learn about the Slipgate device and Operation Counterstrike before diving into the action.

Alright, so you've just gotten this call at 4 AM, and by 5:30 AM, you're already deep inside a secret military installation. The commander's laying it out for you: it's all about this 'Slipgate' device. The idea is to use these things for instant transport of people and cargo. Sounds pretty sci-fi, right?

But here's the kicker: some enemy, codenamed 'Quake,' is using their own slipgates to drop death squads right into our bases. They're killing, stealing, and kidnapping. And the worst part? Nobody knows where Quake is from. The top scientists are guessing he's not even from Earth, but some other dimension. They're saying Quake is gearing up to unleash his *real* army, whatever that is.

You're the best hope they've got. This whole thing is called 'Operation Counterstrike,' and you're in charge. Your mission: find Quake and stop him. You've got the green light to grab whatever you need. If these eggheads are right, everyone else's lives are basically expendable at this point.

Now, while you're scouting around the base, you hear gunfire. Damn, Quake's forces are fast! You race back, only to find the place completely overrun. It's a grim scene – you're pretty much the only one left standing. Operation Counterstrike is officially over, except for you.

Here's your only shot: you know the installation has a slipgate at its core. Since Quake's goons came through it, it's still locked onto his dimension. You can use it to jump into his turf. Maybe, just maybe, you can get to the guy himself. You load up your shotgun, take a deep breath, and get moving.
