Anyway, I change positions alway`s. I never stay in the same place very long. Even if its just alway`s moving between two places or so, but never stand completly still for more than 3 seconds, and that might just be to line up a shot! But you should be able to do that on the run!

And alway`s aim for the head, but wait for them to stop moving and attempt to do somthing else, to make your move. That, or don`t let them in your tunnels, either way!

And don`t shoot at the harvester, I do it all the time but I really have to stop. It gives away your position, and also takes away much needed ammo. It might not seem like much needed now, but wait until you run out...at the worst time. As Murphy`s law states:

"Everything that can go wrong, will go wrong, and at the worst time!"

So keep your ammo, until you need it!

OH, and don`t shoot vehicles, wait for them to get out and repair their vehicles, then strike. STRIKE WITH A VENGENCE!!! Then use their vehicle to destroy their harvester, just to put hurt on top of agony!

Enjoy!

Peace
