HARD: KR MOD: Rotwick - Undead Only Challenge 2 - Impossible Difficulty/No Hero

This is the KR MOD ReBBBorn and we are attempting an "undead only" challenge on the stage Rotwick. Though Rotwick may be undermined by many as the least difficult of all elite stages due to every enemy appearing possessing a low HP pool, this challenge is not to be underestimated. First off (and obviously), the bump up from veteran to impossible difficulty is already enough to make this stage all the much harder. Second, our towers that primarily specialize in one-on-one combat. This is disadvantageous for us on this stage because they overwhelm us with a large number of enemies and ambushing. Since the foes HP has gone up significantly, our efficiency in killing off enemies matters greatly. We need solid chokepoints and an effective way to kill hordes of enemies. This challenge can put some respect on Rotwick for once. #kingdomrushmod Feel free to like and sub. Thanks!
