D-Fence

Summed up by Funjunkie as involving "big guns, lots of violence and loud bangs", even the authors admit that this one is more than a little influenced by the classic stick-man siege simulator Defend Your Castle - but with all the convenience of a proper shooting gallery like Camper Strike instead of all that unrealistic flinging your opponents into the air.

So, as well as slightly less chance of giving you a repetitive strain injury, D-Fence also offers the opportunity to upgrade your (mysteriously toilet-roll based) defences with repair units and snipers. Again like "Defend Your Castle", the first level is a bit boring (just keep shooting the occasional opponent until the time runs out), but it gets more exciting much more quickly when the guys with bazookas turn up on level 2.
