Your map designers for this game are amateurs. Steel Beast? Liquid Fire? Creature Workshop? horribly designed. too much large distances, and restricted pathways, poor enemy spawn locations and poor enemy AI means your combos get broken frequently, you would need a rifle to snipe quite a few just to keep a combo, instead of continually melee slaughter for that higher score. that need for a rifle puts certain characters at a major disadvantage, what if i wanna use casual Leon? and i don't wanna touch pirate Leon? what if i wanna use business suit Helena? not stripper police costume Helena? these designers cannot have possibly tested their maps. large open spaces with many ways to run to the next area are good maps, only Urban Chaos, Mining the Depths, Rooftop Mission, and High Seas Fortress are good in this game. which is sad since only one of those good maps are not zombie filled, i like fighting the mutating soldiers, they offer a better challenge than zombies. now that i've unlocked all maps and had a taste of those maps, i'm sticking to the only 4 good maps in mercs mode. for all game developers out there, please make it a point to force your development team to test out their work.
