Marsec High Explosive
The High Explosive is very powerful, but almost impossible to throw; even with 100 strength, an Agent cannot throw the High Explosive far enough to be outside its blast radius. Agents can use it to increase the power of Proximity Mines, but in this regard, it really has little advantage over multiple AP Grenades and is totally outclassed by the Vortex Mine.
"A high explosive system for breaking through barriers or impassable terrain. Extra care must be taken when throwing this device. Its increased size means that it can't be thrown the same distance as a conventional grenade."
