I'm playing on a pretty low difficulty thus far, and I reload whenever a unit has a calm moment. I'm used to games like Call of Duty, where your ammo is just in a big pile until you put a new magazine into your gun, and unused ammo in an old magazine is returned to the pile. Therefore, it behooves you to reload early and reload often.
However, in XCOM I'm not sure how ammo works exactly. Of course, there are clear shot-limited weapons (like grenades and rockets), but I don't even think I've seen any indication of how much primary/secondary ammo I have left, besides the current amount left in a magazine. (This is indicated by the "blue" hue of the gun turning gray every time you take a shot).
Is ammo in primary (ie, assault rifles/shotguns/sniper rifles) and secondary (ie, pistols) weapons limited? If so:
- is it "magazine" based (ie, my soldiers carry N magazines, and reloading loses any unfired rounds in the old magazine) or
- just a general non-specific count that can be used in however many magazines you choose to use?
Does this vary with difficulty or weapon types in these slots?
