Survival mode! – Peacekeeper: Protect the base in this defense game Review

This is a very good game, it's simple but challenging. One thing that would make it better would be if you could have a survival mode where you just shoot stuff until you die. I'm not too far into the game, so if there is a survival mode that you just unlock or something, I'm sorry for wasting your time.
