Fisticuffs guy: No matter what the enemy, they must perish from a heavy melee attack. This guy shows no fear in the heat of battle, but welcomes the advancing oppponents, challenging them to a brawl. Guardians cringe in fear at the thought of a fist going through their mail slot. When all enemies are defeated, he will resort to meleeing his teammates to keep his fists from becoming rusty.

The master strategist: Every single wave you must adhere to the commands of this great tactitian, giving out orders for you to follow, almost like you are a member of his squad in single player. Make sure to save your abilities for when he tells you to use them, otherwise you must face his wrath.

The full extraction is the most important thing in the universe guy: This guy will not only yell at you if you do not get into the circle IMMEDIATELY, but he will use an unquantifiable amount of rocket launchers during this wave to ensure that full extraction is complete, even if you are all level 20. You wonder why he didn't use those rocket launchers while you were hacking an objective against reapers on gold.

The Olympian: This guy wants to get as many gold medals and awards as possible. This is why he wields a sniper rifle and shotgun as a sentinel, specced into melee combat. He will melee, revive, grab, use biotics and tech, charge into combat with a shotgun, and snipe. All for the sake of getting those rewards at the end of a game.

The Vanguard with imputiny: No need for an introduction,this guy is infamous.

The roll guy: Walking and running are overrated, this guy will roll to all his destinations. He will bait rocket troopers to shoot at him, banshees to grab him, phantoms to pierce him, all for the sake for his extravagant display of rolling. He is very fond of the drell rolls.

The grab guy: He will sit in cover for the entire game, waiting for that decisive moment to grab an enemy and pierce him with his omniblade in epic fashion. Unfortunately he will be clumsy with the timing and will eventually pop out of cover to melee the pyro burning him, and die. Fortunately he has an inexplicable amount of medi gels and will find a new base of operations to perform his signature move.

The Altruistic guy: No matter where you are or how many enemies are surrounding you, this guy will do whatever it takes to revive you. Even if he is in the middle of capturing an objective, he will cancel it in order to save his comrades. Favorite of the Vanguard with imputiny.

The Lone Wolf: Runs off to do his own bidding as fighting with a team is cowardly. While you are busy hacking an objective, surrounded by banshees and brutes, this guy will make sure that those pesky husks never reach you. If he is dying, you are obligated to revive him or he will quit the mission.

The "ok i'll give him a chance" guy: Most of us have come across this guy, particularly in silver and gold. His n7 rating is kind of low for what you think it should be at for the difficulty level, or his gear setup is wierd, but you figure the rest of your team is good enough to carry the bulk of the load. Unfortunately this guy will get mugged by husks, grabbed by banshees, slapped by brutes and will constantly need to be revived. You blow every missle launcher you have on wave 3, and by wave 4 you are out of survival packs and medigels. Very rarely do you come across an individual who fits into this category, that actually exceeds expectations.

The Elitist: As soon as you join a lobby, you already see an [X] marked on your name. If you are not an asari adept or salarian infiltrator you do not have the privilege of playing with this person, who is usually a low-level sentinel. Because his N7 rating is high enough, he can do whatever he wants. Everyone below him in N7 is deemed to be a noob, anyone above him challenges his existence, and he calls them a no life loser.

The Scoreboard Guy: After every single kill or assist, this guy furiously mashes his tab key in order to see who has the highest score. If he is behind, he will pull out his missile launcher for the atlas on wave 4, or the group of geth pyros on wave 5. At the end of the game he will belittle anyone who is below him, and proclaim to those who are above that they stole all his kills, or that he was lagging.

The Unsung Hero: This guy's contributions are often overlooked. He uses stasis on phantoms, decoys in well placed areas, hacks turrets, and does what he can for the teams well being. It may not show on the scoreboard, but his contributions are significant, even though no one notices them.

The WTF that works guy: This guy will come into a game as an SMG wielding infiltrator, but somehow it works. You usually wonder why you didn't kick him or leave, but it all works out in the end. You try to duplicate his strategy, but get kicked out of every lobby or fail miserably.

The Noob: He will heavy melee guardians, run around with a rocket launcher not knowing how to use it, arm himself with the worst guns possible, and neglect to level up his powers. You would think by N7 120 he would learn by now.

The Rival: No doubt you will come across a game where you and someone else are the same class\race. Your competitive nature comes in, and you actually use ammo powers and other equipment bonuses. You are constantly checking the scoreboard and trying your hardest. You succesfully complete the mission because you both make each other better, but you loathe their existence even when you aren't directly competing with them.

The Rager: Before the mission even starts this guy is going insane, yelling at you for no reason. If you get a kill, he will accuse you of stealing it. If you complete an objective, he will yell at you for not doing it faster. If you are playing a low level character, he will yell at you. If you use a rocket launcher without his permission, he will yell at you. If you do not get into the hacking bubble immediately, he will yell at you. If you take his thermal clips from an ammunition crate (even though they respawn), then god help you.
