Crossbow defroster test as an inventory option. Direct fire and two rounds. So in effect you can have one EMP nade and two of these. Only affects the player hit as a balance for its long range and accuracy. Compared to the standard 'use button' defrost its fire and forget nature allows for safety. So its a choice between a short range throw that might be close enough to get a group or a single highly accurate longer range shot. The vid shows making kills with it but that is for testing only.
On a different note, considering limiting remote defrosting to all primary.secondary weapons. No inventory items. Thought about a 'defroster gun' of sorts. If you want to defrost you must switch to that weapon. Cant use your rifle. It would be pretty interesting but likely too different.
