You can aim high and longball, you could also do this in speedball from back to back
The alternate is to get closer
Woods all is in bigger fields to allow you to spread out, sneak around, have other features such as buildings, bridges, static vehicles. To go hunting for objects
Scenarios differ from ordinary paintball such as speedball which is played as a sport, woodsball which has common goals as the rest of paintball such as capture an item or objective, hold an area, protect or attack a VIP
In scenario there is a storyline. The game could be detailed around that, or just be a loose story and have standard types of objectives, or can have complex objectives, items to be found, gadgets to be assembled, things to blow up.
You can just go out and shoot people but the core of the scenario and be way to win is to play there objectives of the scenario
You can get guns that shoot further. But unless you are using a flatline or an apex or are shooting first strike or any other 'wonder paintball' with fins etc then the deciding factor is your muzzle velocity and efficiency in the barrel with regard to paint match etc. this is the same for the woods or tournaments
