Very Creative game, i wish better graphic, more monsters, more defense buildings, more things to do with ally monsters like-equipment, moving them, or (take action from first person maybe ) :)
there could be another ( with higher difficulity) weapon tasks to do after first... to combine between collimators, scopes, sights, magazines or changing bullets. (last task for build in granade launcher into m4 ) hehe
Wow, you stuck with it though!
