They really need to add weapon testing. I got the Steeled Veterans wb for the flame breaker and it turns out I fucking hate that gun. Now I'm out the 1000 SC I grinded for
You should give the incendiary breaker a second shot, it is the best shotgun in the game and by far the best weapon against bugs, as long as you have a good support weapon for chargers and titans.
I run IB/Grenade Pistol/Incendiary Contact nades/Quasar in diff 7 and 8 missions and am usually above 250-300 kills per mission.
I think I prefer the slugger against bugs, tbh. Requires more aim but you can shoot right through most armour. Makes it way more economical to kill armoured bugs.
With this release I'm convinced the illuminate are just around the corner.. Giving us the closest possible load outs to the characters from predator seems like the final piece of the puzzle they've been working on for so long.
