Well, i made it to Under The Radar in HL2: Ep 2, and i was at the part with the radiation, the powerful turret shooting at all the zombies, and a house with healings, and another house with 3 or 4 Combines (One had a shotgun), i had low Health, and i just barely made it through the Combine fight with only 2 points left! Then later, i figured out how to destroy the turret, so i did, then i got back to the Rebels who were fixing my car and i had to drive with only 2 points left still, then after finding the first radar cache, i found a bunch of healings, thank God, but after the Advisor appeared and whatever and left, i made it to the second house which i considered a safe house due to all the healings and ammo, unfortunately that;s when i tried to drive off, but all of a sudden, the Combine gates activated and i hear Alyx yell "It's a trap!", so that;s when Combine are storming my house and i got 3 Hunters after me at the same time as the Combine, so me and Alyx almost die trying to take out the Hunters in the house (After they break in), the funny thing is this, i think "I'll go down to the basement for some healings", but that's when i see a Hunter in there, so there goes that, but eventually, without any deaths, i managed to get passed all that and make it to where you gotta use the Gravity Gun to kill off the Reactor in, if i remember correctly, a garage the Combine were protecting
I hate Combine and Hunters, also despise Zombines!
