I saw Victor's post on mirrors or cameras to see around a corner, and having just lost 2 guys to the same corner in one turn I was thinking about how deadly the corner can be even with the reduced accuracy. So I was thinking that if there was a relatively cheap option like a smoke grenade that would last for just a turn or two and further reduce accuracy, that would be something I'd certainly use to increase my guys' chances of survival when rounding a sketchy corner. It could potentially make the Opp Fire slightly less effective as a strategy, but it would also affect the shooting of the side using the grenade too. I think the camera/mirror is a more elegant solution in theory, though I'm not sure about the programming side of it, but figured I'd offer this option as an idea too.
To me that sounds like a much more practical idea than the camera/mirror. Smoke grenades/Flashbangs have been mentioned before and are another element which was used in Sabre Team.
The smoke grenade could mask movement for it's duration and therefore disable opportunity fire against anyone moving inside it's radius.
A Flashbang could also be implemented as a cheaper option than a grenade to throw at corners and would temporarily blind (and deafen) enemy units, again disabling opportunity fire.
The gaming advantage with these is they must be bought so you would only have a limited supply of them as opposed to the camera/mirror which could be used over and over again on every corner.
Hmmm...I don't know about being completely immune to Opp Fire, that seems like a huge bonus, even if it's limited by the # of smoke grenades you take. I could see it being knocked down a category of accuracy, depending on how long it lasted.
Although if it complete obscures sight, would that actually accomplish anything? You'd have to move through it to be able to see a target. I suppose you could shoot blindly down the corridor, which you can't do now, which severely weakens Opp Fire since it's an auto setting and the OF unit would either a) shoot automatically at reduced rate if the smoke partially obscured vision, which would mean the thrower could wait until the max two OF shots were taken and then step through the smoke to get a clearer shot at OF unit, or b) Stand there looking dumb as someone popped smoke, stepped out behind it, and sent a flurry of shots their way.
I was thinking that a good use would be to pop smoke, step out behind it to see if there was anyone in the corridor, and then be able to step back into safety if the shot didn't hit. But in retrospect if I had multiple units I would use the smoke grenade differently if it just reduced vision, waiting until the unit took the OF shots and then moving through the smoke to get a better shot.
I guess it's going to be in limited situations that it would be a significant advantage either way, but I'm personally up-in-the-air about which would be better (totally obscuring vision or just reducing accuracy).
Maybe this smoke granades are better choice than mirrors, I agree with Deadlime that abusing of that feature may change the gameplay. With granades you have to change item, prime and throw it, so you'll use them just in certain moments, some corners, getting into a room...
