This is my weekly run of tower defense - infinite zombies. I scored 43.7K without any A-bombs - which isn't a bad run. I talk through some tower placement strategy for those that have requested some more commentary in addition to many walkthrough's that are available. There are many formations and I welcome tips from those who can score 48K regularly too.

Some tips:
- a lot depends on luck of wave end rewards, don't get frustrated if you don't get same results
- a lot depends on starting bonuses of laser and rocket towers (+240% is max)
- you can replay any level by pressing the back button (as I did many times on last level 11)
- you can only restart entire game up to level 3 (or level 4 before you accept wave end rewards - need to exit game)
- you can replay during the week if you have a bad run, but minimal benefits unless you can get top 5 or higher
