[MOBILE] [LATE 2000's/EARLY 2010's] Zombie "defend your castle" type game

there was a zombie game on IOS that took place in like a really drab grey world and you had to defend a tower in the center from zombies coming from either side, you could pick up the zombies and throw them so it kinda worked like defend your castle on wiiware. i remember my mom used to play it with me and she would yell at me for being bad like a teammate in counter-strike

its not hell zombie
