At what range do various weapons get range bonuses?

Solution 1:

There are three types of weapon range available for player characters: Short, Medium and Long. The exact bonus/penalty changes a little depending on tech level (conventional, magnetic or beam).

• Short Range applies to shotguns, it gives you up to +40 aim at point-blank range and up to -30 at extreme distances with +0 modifier at 11 tiles.
• Medium Range applies to most weapons and gives up to +20-22 bonus aim at point-blank range with no long range penalty and slower drop-off.
• Long Range applies to Sniper Rifles and is actually the easiest to account for because of its linear nature. They give -30 at point-blank range and +0 at 11 tiles. Long Range weapons don't give you an aim bonus.

Weapons don't have crit bonuses from range unless they are equipped with a laser sight. The bonus is +10 at 0 tiles distance and drops-off at a rate of 0.5 points per tile.
