[Medic] It’s a bad idea to charge your paddles or Reviv-r when the person you want to revive is in the open. Not only do you move slower, but there’s a good chance the enemy will finish off your patient before you get to tend to him or her.
[RedEye] Be careful, your team can’t see through your smoke as well as you do. Don’t throw it in the middle of your team and the enemy team. Ever.
[Phantom] Moving slow is the way to conquer. Sprinting always makes you visible, even at range. Walking keeps you covered from long range. Crouch-walking is enough to fool people up close.
[Phantom] Katanas are cool, but guns are far more reliable. He has some of the best SMG’s for a reason.
[Phantom] Your cloak generates sound while moving. If you’re already behind a group of unsuspecting enemies, you’re often better off dropping your cloak as you move in.
[General] Glass ceilings (such as over the EV on Bridge) block the Orbital Laser and Artillery Designator from locking on to the ground beneath. Break them in order to use these. In case of the Orbital Laser, it can then move freely as it breaks any glass it runs through.
[Ammo] Throwing ammo directly at a player reduces his/her cooldowns by 15%. Especially Skyhammers will appreciate it if you throw a few after they threw an artillery strike, but don’t forget the people that genuinely need ammo!
[General] Your knife is an important tool in Dirty Bomb. Get used to switching to it quickly, as it allows you to quickly escape and to finish off players with a quick slash. Of course, you can also use it to slit the wrist of that Proxy as she jumps past you!
[Stopwatch] The enemy respawns at the same time you do. Take this into consideration if you’re about to make it rain on an enemy camp. Timing is key!
[Vassili] Be very careful of the temptation of sniping. While he has his purpose in suppressing enemy movement, scanning positions and taking down heavy troops, his killing potential is often more limited than that of other mercs. Especially when it comes to objective play, it’s more important to be close to the action. «He is undoubtedly the worst mercenary for new players, solely because he’s playing his own game»
