In online games, it is not uncommon for this type of battle to occur as a duel. In this case, you are fighting one on one with the enemy, using the same types of weapons whenever possible. There are many variations of games that can be played one-on-one, and there are just as many specific recommendations for each type of game. Still, there are tips that work for all types, and if you use them, it will significantly increase your chances of winning.
First of all, build your strategy from defense if you are not confident in your skill. Houses and walls help - fortify yourself at the base and analyze the manner of the enemy's play, try to understand what style of play he is more inclined to, who he is in class - a sniper or attack aircraft, what weapons he prefers, how he moves. Do not take the initiative until you are confident in your abilities.
Do not stay in an open place for a long time and do not stop at all. Regardless of the class and skill of the enemy, if you stay in place, you are already a corpse. Use fast movements in order to assess the level of the enemy. Do not disdain cover, change them as often as possible so that it is impossible to predict your next move.
Choose three or four basic strategies and combine them. Your main task is to be unpredictable. If you don't rely on your reaction, the optimal moment to fire from cover is right after the enemy has fired. If he is an attack aircraft, it will take him time to reduce the spread after the first shot, and if he is a sniper, then it will take him a long time to reload.
And finally, count the cartridges. If you can't count the enemy's ammo, count at least your own and save them. Many duels were won due to the fact that by the end of the shootout, one of the players ran out of ammo, while the other still had them.
