Today Me and my other friends were thinking about Jackbot XL as alone standing Challenge. It would be similar to Sudden Death Blitz mode (Infinity Rounds) but only bot that spawns is Jackbot XL. Yeah.... just Jackbots XL nothing more... Each 3 Jackbots XL get upgrade (change color on other), to pretend people from camping on one. This mode would be interesting because It's fun using Annihilator on Jackbots and kill 'em by 1-3 shots.
If a game mode is made fun by the annihilator which has a ~5 min cooldown, I think there are some fundamental flaws that need to be worked out.
Well I think they could mix it up just like with Scramble Blitz (Gremlins). Jackbot is not hard to kill when you have 3 friends and turrets (Of course we are talking about one Jackbot). After several rounds just like Scramble Blitz the Mascot appears to give you bonus. You use the bonus to upgrade or buy juice and again kill Jackbots. When You'll have 8+ Jackbots then yes you need to use Annihilator. And one more thing. Don't forget about buying Juice. After 3 waves the mascot appear but only to 15 wave... later player needs to survive on his own (Sudden Blitz after 50 waves you won't have a break to relax for few sec)
It's possible to do this solo. But only 1 jack bot spawns per wave. Quite good for cranking up jackbot kills and bacon pickups. Just type "open dlc1_spunky" in console. After round 10 it's just jackbots.
