once you find out where the crit hit areas are on the enemies they seem to drop like flies with the assault rifle fully upgraded.. it did annoy me that the highest lvl weapon was always equiped every new wave, not trying i was able to get around the top 10 ranked for the maps i played i find this game rather easy, it gets repeative fast, although i only played up to lvl 20 or something like that wasnt really paying attention. the reward list or lvl up list whatever you call it at the very bottom of the screen it would be nice if you could turn it off because i really dont care what everyone else has unlocked or when they lvl up.
the gameplay has been done over and over again nothing really new here
there is very little weapons to use
power ups need hotkeys
instead of unlocking weapons at x lvl a shop would have been better in my opinion
main menu seemed a bit cluttered.
more upgrades to pick from would have been nice.
being able to pick your survivors along with lvling them up would have been better than just an upgrades list since they seemed very useless even at max lvl.
maybe make the map more interactive, with placeable walls, traps, having grass burn for a short period of time, explosions have a small chance of leaving a hole which slows enemies...
