Official Tips From Gameloft
Each weapon has a Weapon XP Parameter, which represents how much the player is attuned to that particular weapon. Weapon XP has three milestones that can be reached at 30 percent, 60 percent and 100 percent.
Reaching a weapon milestone unlocks basic upgrades of various types: Clip Size increase, Critical Chance increase, extra effects (incendiary bullets that set enemies on fire, bleeding or concussion for melee weapons), Damage increase (general or versus vehicles), longer effective range, no movement penalties, etc.
Each weapon has a Durability value. Weapons decrease in Durability with every shot, and the lower the Durability, the less satisfactory the weapon's performance.
When a weapon is in top shape, it has an increased chance to deal double damage.
When Durability decreases, the chance to miss increases, and other penalties start to pile up: slower rate of fire, increased reload time, less damage.
Repair weapons regularly so they remain at maximum efficiency.
In Domination, the goal is to be the first team to reach 30 points. Points are awarded for killing enemy players and holding flags.
In Team Deathmatch, you get points only for killing enemy players. First team to reach 15 points wins.
There are three vehicles in the starting zone for each team: one 4X4, one tank and one helicopter. If a vehicle is full, you cannot get in and the Interact icon will not appear.
