1 Always with the explosion . It applies with or without the explosion , but since the explosion damage can only help you , it ' s in your best interest to have it explode . 2 M 79 RPG , as that allows you to actually kill HVTs efficiently . The only real purpose for the M 16 M 203 is as a replacement for the M 79 in the RPG loadout they weigh exactly the same , so if you want to deal with trash more efficiently up close , sell your M 79 when appropriate to get the M 16 M 203 . Personally , I ' d rather offperk a doublebarrel than spend 1200 on the M 16 M 203 , considering how the M 203 does significantly less damage than the M 79 , but it ' s personal preference . 3 LLLLL . The reload on the M 79 isn ' t that bad , and you have enough explosive ammo with the passive that at 25 , the 5 more rounds doesn ' t help all that much . If you do go R on the first tier , go R on the second tier , as you will need the additional rounds . Personally I ' d rather get the bastard in fewer rounds than less . For the boss round , depending on how much dosh you have , you might want to go R on second tier for more ammo . 4 Playing your role mainly the HVT killing with the RPG is essential , as your team could be relying primarily on you to burst down HVTs . There are numerous other classes that can deal with trash i . e M 16 M 203 , but the only other class that does anywhere near the burst damage that you can do as Demo is Sharpshooter . Focus on getting the RPG after getting the M 79 .
