Half-Life 2 Hints
What are these little glowing diddly-things that attach to the jeep?
1 of 7: Those are rollermines.
2 of 7: They don't explode like regular mines, but one of the annoying things they can do is attach to the jeep and give it a powerful jolt every now and then to make you lose control of it.
3 of 7: You don't want those things on there, so hit the handbrake as soon as one attaches itself.
4 of 7: Get out of the jeep and use the gravity gun to yank the rollermine off the jeep, then turn and fire it out into the ocean. There's no coming back from that!
5 of 7: Better yet, drive along slowly and scan for inactive rollermines ahead of you in the distance.
6 of 7: Whenever you see some, stop the jeep, get out on foot, and go get those mines with the gravity gun before they can even start causing you trouble.
7 of 7: WARNING: Don't let a rollermine run into you while you're on foot, since they can deliver their powerful charge into you as well as into the jeep.
