Location Location Location

This is one of if not the most important part of playing Demolitions. You need to position yourself in a location in which you are a safe distance from ZEDs, have line of sight on the ZEDs for firing on them, you are not in anyone elses way, and you are not near any of your own Pipe Bombs. This is usually behind your team or on an elevated portion of the map. Also, a very overlooked and often forgotten about aspect: Pipe Bomb placement.You want to maintain a position that allows for a cushion between you and the ZEDs. As Demolition, you will damage yourself if you fire at ZEDs that are too close and you will fire duds if the ZEDs are in your face. A common thing I see that Demolitions do is when they spot a fleshpound, will run to the front like a hero and perform a combo. This sometimes works out just fine, they remove the Fleshpound, and run back to their spot in the back. However you do not need to run to the front. In the event you do not perform the combo correctly, you will have a raging Fleshpound running straight at you causing you to either damage yourself as you shoot at it while it encloses on you, or do almost no damage at all as it hugs you with it's drilldos. The cushion will allow you more time to aim and shoot grenades at the Fleshpound, and if you have a Medic inbetween you and the Fleshpound, hopefully the Medic is tanking any potential hits and you are far enough away to not blow yourself up as you finish it off.Location of Pipe Bombs is just as important. Don't get too excited about having Pipe Bombs and lay all 8 before trader time is up where the team is camping. This sometimes works out, but more often than not, a siren wanders in at one point and screams away 5+ Pipe Bombs after or before the first set of Fleshpound(s) were dealt with. Also do not lay Pipe Bombs out of the line of sight of where the team is camping. This is a bad tactic because it is a surefire way to have a surprise raging Scrake or Fleshpound come running out of nowhere. A very dangerous surprise.A better tactic is to concentrate on how you want to use your Pipe Bombs - defensively or offensively.Offensive Pipe Bombs should be used sparingly and laid as you need them. This means during trader time in spots where you know Fleshpounds will walk over them when the wave starts, or you have spotted a Fleshpound and are laying one in it's path. Pre-laying Pipe Bombs in the open rarely works out and are almost certain to be set off by trash specimens, Scrakes, or lost in Siren screams.Using Pipe Bombs defensively can literally be a life saver. This is when you place Pipe Bombs in areas you know teammates will fall back to when they are either being overwhelmed or run at by a raging Scrake or Fleshpound, and are usually gaurded by objects or walls of the map. Where you lay them is entirely dependant on what location you are holding within a map and requires strategic forethought by a Demolitionist about where your teammates are going to need the help, and where you should put the Pipe Bomb as to not get siren screamed or blown up unnecessarily.For an example of this, I will use the spawn location on Biotics Lab.The barrels make great barricades for Siren screams and most decent teams can hold back the horde to a point well before the first barrel down the long hallway. Placing a Pipe Bomb behind this barrel means that any group of specimens that makes it past this point will be blown up, or if a Scrake or Fleshpound make it there, they will either be stunned or have a great deal of damage dealt to them. This is a 2nd line of defense - if the team can't hold the line, maybe the Pipe Bomb will blow the line a little bit farther away.Emergency Pipe Bombs can also be very helpful. When the team is in trouble, usually they will retreat down the side hallways towards welded doors, and the back portion towards the elevator.Laying Pipe Bombs in these areas can protect them from being overwhelmed - which is probably the case since they were forced to retreat in the first place. It is important to leave one of the hallways clear of pipes for yourself to retreat down. You do not want to ever be on, or have to retreat over your own Pipe Bombs. It's a surefire way to blow up if you're being chased by specimens. Placing Pipe Bombs in these (see pictures) locations will keep 2 of the possible retreat areas gaurded, and leave the back-right hallway for your own retreat. This area is safer for you to retreat to with teammates because if needed, your team can hold the hallway and you can locate yourself in the room, firing through the window, keeping that cushion between you and the zeds to prevent blowing yourself up.Place a Pipe Bomb behind the barrel to the left.Putting Pipe Bombs here will save teammates who are pushed back by a horde or raging ZEDsPutting a Pipe Bomb halfway down this hallway, maybe using the barrels as a guard will help save teammates who are pushed back this direction.Keep this way clear for your own retreat - you don't want to be blown up by your own Pipe Bombs.Putting Pipe Bombs down the hallway can be beneficial at the start of the wave. Make sure they are in line of sight of the team so you can see the Fleshpound(s) as they rage, or deal with Scrakes that set them off.Similar tactics can be applied on different maps.The concept behind this is finding places where your Pipe Bombs will be able to save your teammates while at the same time protecting the Pipe Bombs from non-emergencies, and stayingaway from your own Pipe Bombs. This can be applied on many maps in many situations differently.
