Yeah um this game is an acrade like shotter, you spawn in a city and after sometime some buildings get raided by bad customers. when you "kill" the raid you get points that you can spend in the upgrade bench. but when you upgrade the difficulty also goes up, and every 10. difficulty a speciel wave of enemies will come after you, and depending on the type of enemies you will get a speceil upgrade. also its not done yet
