I have a question regarding objectives in Multiplayer. So lets say you want to go help your team out and you want to go open a door or repair a crane or take control of a command post, but at the same time someone on the other team also wants to do that objective, can you both do the same one? If that is the case, say that person does the objective for the team, does the whole team get the same amount of XP or does the player that did the objective get the XP? Just seems weird having side missions while playing with other people online. IDK how it would work

Missions are one sided. Only 1 team will have to open that door. The other team works on closing that door. Command posts can be captured by both teams so you fight over the post. Only the player gets the xp.

Some objectives, like build/repair and hack, can be completed cooperatively. I don't know exactly how the xp is portioned out between the players completing the objective, but I would imagine it is based on percent of interaction.
[e.g. Say you receive 1 xp per percent of objective completion accomplished while interacting. If another player comes and assists you would still receive the same amount of xp as if you completed it by yourself. If the other guy shows up at 75% completion, he would receive only 25% of the experience you earn upon completion.]

I'm pretty sure that I heard somewhere that once you accept a mission from the objective wheel you "take" that objective so that griefers can't just go around stealing people's objectives. However, you can speed up the progress of some objectives by joining in and helping. Of course, I could be wrong.

I also have a question about the side Objectives.If i play Medic, would my current objective change to revive "insert name" automatically as i move towards a down ally or would i have to tap up on the d-pad?

I think you still have to select it, but I guess we'll see.

imho since SD are making balanced games and made this a teamworking game. i think that the one that complete the objective get a good amount of XP and the rest of the team gets a little bit of it. otherwise what would stop the whole team to become operatives and complete side obejtives for their own profit. i could be a bad company 2 sniper issue were everyone wants to be the sniper and so on. but this is just something i think. nothing of this is comfirmed as far as i know

The fact that not everyone wants to play operative. sigh

Take the following example.

8 players join a game on the same team.

Everyone goes Operative and only does side objectives.

They're meant to be defending, and the enemies aren't idiots.

For some strange reason, their lack of defense on the primary objective results in the enemies winning almost unopposed.

If they're on offense, great. They go for side objectives instead of the main objective, the enemies all camp the main objective with the "defend" option selected in the objective wheel, earning a constant stream of XP while the Operatives rush about trying to beat one another to the handful of side objectives, many of which require them to change classes (which they won't do, because they all want to be Operatives). So two of them get to capture CPs, and if the team is REALLY lucky, another two will firewall the captured CPs so more than just the first two players earn XP. Maybe one more gets to hack something and unlock a side route somewhere in the map. Awesome. They still lose before completing the first objective.

As much as I love the operative 1-2 is all you need.

Now the way i saw it in the Get Smart Series was that more than one person can be on objective, I believe this because you can see a number in the objective wheel that corresponds with each objective. It would not be stealing an objective It would getting it done faster, If we could not than one loser on your team could "take" the main objective and stall or be awful and end the round early.

From what I understood from the dev interviews, the objective wheel is just a tool to help guide the player and to coordinate better in random teams. You don't need to have the objective selected to be able to complete it and gain exp for doing it, its not like taking "quests" in a MMO So there wouldn't be "taking" objectives and thus no wannabe griefers stalling teams.

Example: If you see a neutral command post, you cap it, you get the exp for doing it. You don't need to bring up the wheel and select "capture command post" and them do the objective to gain the exp. At least thats how I understand it.

in fact, you DO have to select that objective, and there ARE lots of side quests. the difference is that many times there will only be 2-3 people who can see that objective and get XP for it until it is activated. once it is activated, everyone on the team sees it and can get XP for helping you out.
