Yeah caveira needs ano indoor grapple hook. That would be ill but people are always going to hit the hatches.There are a lot of indirect ways to set sound alarms in this game... mainly with specific doors you board up.
I think they should swap out some Defenders barbwire for deployable ropes/ladders that they can use to get blown hatches with. Take away Caveira's and Frost's barb and give em that and Attackers have a lot more lanes to worry about and watch.
I mean alarms that you can place anywhere. Close quarter alarms so you can pinpoint the enemies exact location.
A loud alarm would be I'll because now both parties don't know if they are going to have to attack or defend since footsteps are muted in the vicinity of the alarm
