How do you get 48 Accelerators? Well, you have 6 people, yes, because placemat limit is 8. As you can see, only FOUR people can trigger the Hidden Wave and no more. Well, it's that simple. 2 people leave on the last wave. First, they must max out their troops to actually help, then leave. See how simple it is? it is better than having four people trigger it because you have a limit of 16 towers to place with five or six people. ≈20 (I'm not sure) towers can be placed by 4 people. Now, let's do maths. 6 x 16=96. 4 x 20=80. You can see there is a max of 96 towers with 6 people, which is a lot, meaning you would deal more damage to the coming enemies. 2 people leave because, as you should know, you can't trigger the Wave with 6 people. So now you know. You could try this out yourself if you are quick enough!
