While It Is Hard, If You Have Beaten It On Hard, This Won't Be Much Harder.
Try To Get Through Each Level As Fast As Possible, As That Will Keep The Number Of "Giant Enemy Crabs" To The Minimum.
I Think I Destroyed The Opposite Facing Cliff Portals For Levels 1, 2 And 3.
I Rushed The Cliff Portal On Level 4, Took Me 3 or 4 Dumpsters To Get Through All The Enemy Spawns.
After Clearing Most Of The Mall, You May Find Yourself Stuck On The End Portal, With Seemingly Infinite Enemies In Your Way.
- Here's Some Tips For Getting To The End -
You Want The Turrets In Front Of The Cave Portal Built For Sure.
- I Used These On Hard, But Did Not Actually Need Them On Hardest, As I Beat The Game In About 40-50 Total Days, So It Was Not Spawning Incredibly Deadly Retaliation Waves When I Hit The Portals.
The Last 3 or 4 Wall Segments - I Never Built.
- Building All Of The Turret Towers And Barricading Them, Protected My Front Line And Let Me Backpedal Away From Everything. This Was True For Hardest As Well, With Three Turrets To Walk Past Before The Enemy Ever Saw My Walls.
Backpedal Away From Every Large Enemy, Never Let Your Dumpster (Siege Breaker) Take Those Hits Unless You Have To. (Big Crabs Can Catch Up)
Push Your Way Up With The Dumpster Until Another Big One Spawns.
- Then Keep It In Range Of Your Archers, But Backpedal Enough To Not Get Hit.
- Dropping Coins As You Pull The Dumpster Back Gets Rid Of Those Pesky Masked Greedlings.
- Big Guys Have Slow Attack Animations And Stop Moving To Attack
If You Get Overran, Rebuy All The Dead Archers, Buy Another Dumpster/Robot Combo, Then Push Up Again.
The Only Waves That Reached Me Were Blood Moon Waves, As The Double Friendly Bike Charges And Multiple Barricaded Turrets Dealt With Most Enemies.
- The Mechanics Bike Charge Will Stop Enemy Crabs, Even If They Are Mid-Charge
- In Cave Advice -
Defeated The Portal? Time To Go Inside!
The Mechanic Will Repair The Dumpster In The Cave! But if You See A Greed Unit On The Screen, She Probably Wont.
- Standing Idle On The Other Side Of The Dumpster From Her Seems To Help Her Decide To Do It In Cases Where Enemies Are Not Present.
Backpedal All The Way To The Cave Entrance To Avoid Taking Big Enemy Hits Or Just To Repair If Necessary.
I Killed A Spawner, Retreated To The Cave-Mouth, Fixed Dumpster, Repeat.
Just Remember To Keep Those Big Guys In Range Of Your Archers Or You Backpedaling To The Entrance May Just End Up Trapping You.
Good Luck!
