These are 3 levels of throwables.
Higher levels Increase in weight and explosive power, but reduce range.
Grenade type ; weight 6 , longest range, lowest dmg
Demo pack type ; weight 8 , mid range, mid dmg
C4 pack type ; weight 10, lowwest range >>> range 3 tiles with strength 45 ---- range 5 tiles with strength 90+, highest dmg AND higher blast radius (even one tile plus blast radius over grenade is good)
C4 should be throwable AND activated by trigger. This mechanic promising a lot of fun.
