The games seem to be nice and quick. My crew rolled up a lot of long range weapons luckily and so have always managed to get the first shots off unopposed and started to whittle down their opponents. Some enemies are quite tough to take down - eg Hulkers - but even the others can roll high and put one of your guys out of the battle.
There seems to be lots of variation each game with all the different enemy weapons possible, from scrap pistol to military rifles and the nasty plasma rifle. Also unique characters have turned up a couple of times to make things more interesting. There have been a number of different conditions for the battle - dim lighting/fog etc giving reduced range, that sort of thing. And I kept forgetting to roll the random events in the battle so you did well to remember on your first run through.
Excellent campaign system though which means I will keep on coming back to see how my crew are doing. I recommend it to anybody.
