House rule: Popping up from behind a wall.

[kcdusk]

I think your ideas are all pretty good Marc.

I dont know about halving strength though. It seems they are kneeling and/or going to be resting/leaning on a wall. So recoil might be less. But having said that, i think your just trying to incororate a penalty for "snap fireing". So i think either having to make an observation roll (quality of pass or fail determines how much of the situation they are able to take in) or reducing accuracy (even if its a nominal -1 (5%)) would be all you need. I wouldnt do both though, too many rolls, too high chance of failure ... its not an impossible task we're talking about.

But apart from that, it sounds fair and reasonable.
