Maybe if you were like me, when Holdout came out you were expecting something that was just sandbox wave defense like KF2 survival mode (where you can run anywhere, camp anywhere, etc). But Holdout doesn't really play like that at all.
So I edited some maps so that now the only objective is to survive and kill cops for 15 minutes. So basically like Safehouse Raid but without the money piles or the crashing from either Holdout or Safehouse (and also includes some optional buttons/challenges if 15 minutes is too long without getting bored).
Includes Boatload (Watchdogs Day 2), and maps that weren't originally holdout maps like the Penthouse in Mountain Master, and the Shadow Raid part in Meltdown.
If there's people that also actually enjoy something like this and it's not just my tastes being weird I'll take requests on what maps to add next lol.
Stuff people requested so far that I'll get around to making edits when I have time maybe (but not necessarily in order), lol:
Panic Room
Ukranian Job
Resevoir Dogs (I'll probably do Day 1 also too)
Hoxton Breakout Day 2
No Mercy
Buluc's Mansion
Update: Now includes Panic Room too
Update Part 2: Now also includes Transport Downtown, Transport Crossroads, and Boiling Point too
Update Part 3: Added Golden Grin Casino too as an edit
Side Note: (I also recommend to go check out Bank Heist Survival and Mallcrasher Survival by 1LT Alan they are like these edits and are fun too)
Update Part 4: Now you can shoot cops in Big Bank for 15 mins too
Update Part 5: Added Hotline Miami Day 1 to the maps you can killwhore in
Update Part 6: Added Ukrainian Job (I'll get back to Resevoir Dogs later, I kinda bricked the entire save and have to start all over again)
Update Part 7: Now added Goat Sim to the list so you can run over cops as well as shoot them too
Update Part 8: Added Reservoir Dogs Part 2 too now. Also now the maps and the red buttons and the loot that spawn now should actually give XP now (hopefully).
