Right, i'm just going to come right out and say it... but an added C4 backpack would ruin the point of Insidiae's special HUD. So i'd suggest against putting that into a backpack. Honestly, i'd try to avoid added explosives in a backpack as it is. I still maintain that it should be the equivilent of a jump pack. Not the dodgeroller, as that launches you forward, but like a jump enhancer that will give you an extra boost on a jump. For example, rather than jumping 2m you jump 10m every time you tap page up or the e key twice or something. This would allow us to get that little bit of an extra jump but not enough to get banned everywhere. Thus allowing us to jump walls like usual. While I understand everyone thinking it is the same as the boost pack, it is quite different since this would be constructed to move solely upwards. Also since it would only be enhancing the jump rather than causing flight, it wouldn't be banned for moving forwards as well as, and mainly upwards.
