i don't know if i'm the only one that experienced this but there was a bug in the reload system especially on the turret... it would constantly reload without letting me place the turret and some of the weapons wouldn't reload at all... but all in all quite addicting and amusing good job...
i think there is something shiny beyond the top left corner of the map... my units keep running up there and they don't come back... i think they has been eated...
