I recommend the assault rifle to take these guys out because they are carrying ammunition that you can pick up later. If you hear the distinctive clunking sound of a grenade hitting the floor and you didn't just throw one, run away. Make sure to use these to your advantage. There are several explosive barrels in this section that are surprisingly potent. The most important tactic to apply here is to find cover, peek out, fire, and find cover again. This will be your first major battle against the HECU's. When the elevator doors open, a scientist will blindly run forward, showing you what will happen if you do the same. Grab his assault rifle, collect the ammo, and then go on the elevator. Give the grunt some brain surgery with your shotgun to finish him off. Climb up the last ladder and walk across the elevated platform. There are more crates here, one containing a battery. You'll find out what his game is eventually, but for now, just collect the pistol clips, shells, and batteries in the crates, then climb up the ladder. As you go through the door, look up to see the mysterious recurring character in a blue suit fix his tie and walk into the next room. This explosion may or may not activate the fire door switch, so run into the next room if it does, giving a spirited "what's up?" to your fellow scientists (if they survived, of course). When both turrets are down, shoot the laser mine in the next room to destroy the other ones. If you accidentally activate them, immediately run toward the two turrets and fire double-barrel shotgun blasts at them. Two turrets wait around the corner, so jump over the trigger lasers as best as you can. The floors are very slippery and there's a slight chance you'll fall into the elevator shaft. I advise you save it before you go any farther, especially if you have the Source version. Once you have scaled the second mountain of green boxes, drop down, but be careful. If you don't activate them, they won't bother you Smash the first large crate next to the green boxes to pick up five grenades. If the turrets were activated, a well-placed grenade between the two of the should take care of them. A Vortigaunt will spawn behind you, so kill it quickly before he runs over the red laser. If you don't bother the turrets or the red laser here, they won't bother you. Proceed down the next passage on the left, and jump over the red laser at the intersection. Either kill with your shotgun or lure them back through the laser mines, then use the health station at the end of the hall if you need it. This passage leads to a lounge, and as soon as you walk past the soda machines, two Vortigaunts will spawn in the checker-tiled room. In the next passageway, jump over the laser mine and then crouch under the next one. Whenever you see one of these red firedoors, always smash the nearby activation switch unless otherwise noted, as it will block many enemies from coming through. These laser mines explode when the laser is disturbed, so either avoid them or destroy them by shooting the base (black part).Īround the corner is a laser mine and a fire door.

If you murdered the scientist earlier, you'll still have the trip mine to worry about. Charge up your suit until the HEV charger depletes and use the health station if you want. Next to the large blast door is a health station and the first HEV charger of the game. If you shoot the base of the mine (the part attached to the wall), you can detonate it from a safe distance away. They give off very distinctive blue-green lasers and will explode if this laser is disturbed by anyone or anything. You'll notice several of these laser mines throughout the entire stage. You can prevent him from succumbing to this terrible end by shooting him yourself. The scientist then runs off and directly into a laser mine. You'll immediately see a scientist pleading for the blast door to be open, but the security guard in charge of the door gets dragged away by a zombie before he can grant his request. You cannot avoid all of them, however, so your best bet is to run and find cover.Īs soon as the elevator doors open, exit and turn right. These red lasers will trigger nearby security turrets, so avoid them at all costs.
