I'll make 2 examples.

1: Under

There are only five positions to snipe from.

A tunnel entrance
The cliff / either side
Between the bunkers
From inside your base entrance

Where are you going to move too, when all of them take you 30 seconds to get there, and the enemy team relays your position, and you lose your peripheral coverage of your position on advancing snipers and enemy infantry. You stay at your position until enemy armor forces you to move.

2. Field

There are 3 positions to snipe from

Inside the tunnels to counter enemy camping
From either team base entrance
From either bunker which = death

I do not see snipers move position in Renegade MP, and when they do, that equals death both by infantry and vehicles. Good snipers out in deep enemy lines hold position and they stay there even if they have only 10 health left, if they are close to base they may make a run to resupply if they feel like it.

Honestly... there are not many sniping positions on any of the maps, many of them just being wide open spaces inviting yourself to be tank sniped in the head, and believe me, a good driver will take you out with 1-2 tank shells.

Maybe when you die, you may go to one of the few positions to sniper at, but it is all at a loss when...

1. Your team is not controlling the map or enemy entrance

or...

2. You are fighting clearly a less superior force full of stupid noobs and/or your a noob in a noob game... in that case go find a clan and fight a real mans game.

Another useful hint, when faced against an obviously less superior foe who is rushing or taking headshots with a weapon at you, stand your ground, relax, aim, and kill them. Do not under any cir***stances panic

With the addition of air vehicles to walls and city and whatever else map, Sniping will become even more incredibly difficult outside the perimeter of your own base more so if your team does not control the map.

A good sniper has a good team... either its that or your wasting your time just killing and playing with noobs.
