The player can use the R2 or RB button at any time to end deadeye and to cause all marked shots to be completed. The ammunition capacity of the weapon determines how many shots can be marked. The latter provides a critical hit which reduces the enemy's health more significantly.
When using Deadeye, the weapon crosshairs cycles between three positions - a wide yellow cross, a slightly narrower red cross, and a tight red cross. The player can add more slots to the meter by meeting challenges and by purchasing items. The slots are gradually refilled as the player gets kills, with headshots refilling the meter faster. The player begins with three slots in the Deadeye meter, with each slot representing a single use of the mechanic. Red Dead Revolver introduces the Deadeye system (spelled as a single non-hyphenated word in that game).
