Weapons and when to use them

Each weapon fits a different range and playstyle. Choosing the right one for the situation matters more than raw aim.

WeaponStrengthWeakness
AK-47High damage per shotRecoil requires burst control
SMGFast fire rate, strong up closeFalls off hard at range
AWPOne-shot kill potentialVery slow follow-up shot
ShotgunDevastating in tight cornersAlmost no effective range
M4A1Balanced across rangesDoes not excel anywhere

Game modes: Free-For-All and Kill Confirmed

Free-For-All is the standard mode. Every player is an enemy, kills score points directly, and the top of the leaderboard wins. Kill Confirmed adds a layer: enemies drop dog tags on death and you must collect them to confirm the kill. Letting opponents collect your team's tags wipes those points. Kill Confirmed rewards movement and aggression over camping.
