Not bad, but it would have been a bit more impressive if you had used another bunker, because a simple snow singularity bomb still gets through all the walls.
It has High TMP and TMP2 EXOT which turns into super heat warp, which is completely invisible. With snow(sing). The Azure method is using 300-500 life GBMB to direct superheated invisible warp on the material. put undergournd, the warp spreads faster!
Best when put under ground.
Set the life of the GBMB to 350, not 300
