Medium Mode Strategy

You have came here because you want to solo / duo / trio / squad in medium mode to start getting grinding seriously? And start earning more money

(Best Units: Camera Attack Helicopter + Rocket Cameraman + Camera Helicopter)

For Solo: (Autoskip is always on to make game faster)

Wave 1 - Place any unit (Camera Helicopter on back), A few on some parts of the map, most on the front (Always place on front except summoner units)

Wave 2-5 - Max a unit out, then place another, Camera Attack Helicopter + Camera Helicopter + Rocket Cameraman is a good units for this level) 

Wave 6-7 - Place medic and upgrade it just in case toilets will stun your units

Wave 6-20 - Place all your units until you get max upgrade

Wave 20-30 - Remember if you have any farm units that you placed and when you have maxed troops, sell them, and place attack troops.

For Duo: (Autoskip is always on to make game faster)

Wave 1 - You and the other person should autoskip, this time place the units on the front (like usual), and some on the back

Wave 2-5 - Max a unit out then place it again (the Team should do this too) (Camera Attack Helicopter + Camera Helicopter + Rocket Cameraman is a good units for this level) 

Wave 6-20 - Repeat Process

Wave 6-15 - Have medic because some stunning units have more health than a solo game.

Wave 1-30 - Recommended to have some backup defenses on the back as some toilets can go too far (optional), or you can place more once they go too far.

Wave 30 - If all toilets get far from all units on back, sell them and place again, max them too! (No need of medic at this time)

For Trio / Quad: (Autoskip Requried)

(2 people of the team or one of them to autoskip, including you (as it requires 2 people in a trio team game to skip a wave)

Wave 1 - Place your units down, put on front to get a better time.

Wave 1 - Some place on back or any area of the map in tracks.

Wave 2-5 - Max those units and place again

Wave 6-10 - Do it over again

Wave 11 - Place a medic, I recommend you also having AOE Units as some waves here will cause lag and crash the game.

Wave 

Why you lost at a specific wave

Wave 5-10 - You did not place units or maxed them out

Wave 10-20 - Because maybe you did not do the backup defense strategy (max them out also btw)
