Battlefield 4

As far as difficulty is concerned, this is one of the easier multiplayer trophies. Even if you are the worst Battlefield 4 player in the world, you can win a round in each mode without issue. Every mode is team-based, so winning or losing will primarily depend on the quality of your team. Work to achieve the objective of each mode to gain XP and help your team win. Your personal goals (aside from winning) include accruing XP in your quest to reach rank 25 (Call me "Sir" trophy), as well as earning XP while using handguns to unlock the M1911 Handgun and kill 45 players with it (.45 old school trophy).

I unlocked this trophy without even participating in a couple of the modes because the rounds were ending while I joined, and I was placed on the winning team. However, there have been reports to the contrary. That is, some players have said that winning matches that were in progress when they joined did not count for the trophy. If some of your wins came via in-progress matches, you should try replaying modes from the starts of matches. If you join a match that is in progress, you can finish it and wait for the next match to begin. The information below will provide you with strategies for winning each multiplayer mode. You can also use the general tips explained in Call me "Sir" to help you earn bonus XP.

Conquest
The classic Battlefield mode, Conquest requires you to take control of objectives and defend them from the opposing team, as they will also attempt to take control. Each team begins with 400 "tickets" and the first team to have their tickets completely depleted will lose. To deplete the other team's tickets, head to the orange "A," "B," and "C" objectives marked on the radar. There is a flag at each of these locations that you and your team will attempt to capture and control. If your team has more members near a flag than the other team does, then your team will begin to capture the flag, or you will prevent the other team from capturing it if you are already in control. You will earn nice amounts of XP for capturing, controlling and defending (killing attacking players) flags. The longer you control flags, the more your opponents' tickets will dissipate. Teams will also lose one ticket per team member killed.

Rush
The very popular and intense Rush mode challenges your team to either attack the opposing team's MCOM stations or defend your own. This is another ticket-based mode, so when the attackers are out of tickets, the defenders win. The attackers win if they are able to destroy all enemy MCOM stations. As an attacker, earn lots of XP for arming the opponent's MCOM station, and even more for destroying it. Beware, however, there may be several enemy players camped near the stations, and rushing in could be prove suicidal. When you safely reach an MCOM station, hold to arm it. The station will eventually explode if the other team is unable to disarm in time. If you are on the defending side, kill attacking players to drain their tickets. If they are able to arm your MCOM station, you will collect XP for disarming.

Team Deathmatch
There are no fancy objectives here. Just try to kill as many of the other team's players as you can. The first team to 100 kills wins. Playing as the Assault class can help you. You will have assault rifles at your disposal that are effective killing machines and easy to use. You will also be able to heal yourself or your team and squad. Healing teammates and squad mates gives you XP (more for healing squad). Press to deploy your med kit near players with low health. Stand or crouch on a med kit to heal yourself.

Squad Deathmatch
The same principles from Team Deathmatch apply here. The only difference is there are four teams instead of two. With the increased amount of teams, Squad Deathmatches are a bit harder to win than Team Deathmatches. Your five-person squad will comprise your entire team. Help your squad out whenever you can, but be careful when spawning on them, as you may be instantly shot and killed if they are engaged in battle. The first team to reach 50 kills will win the match.

Obliteration
This mode is new to the Battlefield world. The object is to collect a single bomb that appears on the map and use it to detonate and destroy enemy objectives. Dying while carrying the bomb will cause it to be dropped. Picking up the bomb will earn you XP, as will planting and detonating it. However, detonating the bomb is one of the most difficult multiplayer tasks.

As the bomb carrier, you will have a proverbial giant bullseye on your back and you can expect the other team to kill you within seconds most of the time. Hopefully you will have a strong team that can defend you well, because when 10 or so enemy players set their sights on you, you can expect to drop the bomb quickly. If you are actually able to plant the bomb, you and your team will then have to defend it until detonation.

Your team will win once it detonates three bombs, destroying all enemy objectives. You will need to personally destroy a total of five enemy objectives with the bomb, across all plays of Obliteration, to unlock Bomb squad. Refer to that trophy for further information.

Defuse
This is a search and destroy type of mode akin to those found in Call of Duty and Killzone games. Players cannot respawn at all after dying, so you will be forced to spectate if you are killed in action. Rounds will end once all players on a team are killed. The teams are attackers and defenders. The attackers can detonate a bomb on one of two defender objectives to win the round, though this rarely happens. There are two sets of three rounds, with each team having three opportunities to plant the bomb. To win the match, your team must win the most rounds out of six.

Your best bet to win a round is to stay alive. This is obviously easier said than done, but your team cannot lose the round if do not die. Try to be stealthy. Stay near your team and attempt to kill enemy players when you feel you are safe from their teammates. As an attacker, you can plant the bomb (hold on the enemy objective) to earn some extra XP if you wish. This is dangerous, but if you have teammates nearby to defend the armed bomb, then go for it.

As a defender, try to defuse the bomb if the enemy is able to place it on your objective. Be mindful that there may be multiple enemy players nearby and you will likely have to eliminate them all in order to safely defuse the bomb. Hold near your objective to defuse. Try to win a match from start to finish so you do not encounter any issues with the wins trophy unlocking.

Domination
This is essentially Conquest on a lesser scale, so you will utilize the same tactics outlined for that mode, but you may need to be more efficient with your killing. With its smaller maps and up-tempo nature, Domination is where you should spend the lion share of your multiplayer trophy hunt. XP is earned very quickly in this mode, so it wise to play here and accelerate the journey towards rank 25 and the Call me "Sir" trophy.
