my achievements arnt popping up for tower of guns

Do you have notifications turned on and are you connected to Live?

There is a 30G achievement for unlocking all 13 towers. It glitched on my yesterday as well. Mine popped in the middle of the night.

Never had any problems before this but I just liberated all the bell towers and no achievement popped up, seems to be a recurring problem with more than one of us.

You need to do the 'Gotham Base Jumper' achievement from the observation deck way up high on The Wonder Tower, as far as the 'Pay Your Respects' achievement, you need to go to where Bruce's parents were gunned down, any Batfan should know where that happened,
you'll see the outline of their bodies painted on the pavement behind the Monarch Theatre, a cutscene with moving music is triggered by the 'A' button, do wait patiently for the achievement to pop for you have to let the entire soundtrack play out...

I find red gun towers are handy, but if you set up 3 or 4 inferno towers leveled up to red with a tempora set up near by you can toast the smaller bugs. Red cannons can kick butt, but my faithful meteor towers are my favorite. I enjoying just lasering a
full flock for fun...

[/quote]I think about 2 inferno towers, set fairly far apart and hardly ever upgraded past yellow, is going to be the most you ever want. When you look at the cost to upgrade, gun towers trump them. Remember it costs 700 in resources for a red gun tower,
but much more for any other type. Yes, a little diversity can be important, but once you set the aliens on fire then there's little point in setting them on fire again until the first fire has been put out.
