I got these from add-ons on RTB and this site.
GSF Aircraft Carrier (By [GSF]Ghost) (BL Forum)
Got me an idea of this...
GSF Submarine
I know that there already is an Aviator Submarine, but it does not float in water. The reason: Water Vehicles made by Stratosfortress don't float! The only way to make them float is by making an invisible underwater tower and putting a vehicle spawn on top. With collision and raycasting on on the vehicle spawn, but not rendering. I tried that on his Battleship and it worked, but anyway, back to the topic. So blockland should have a realistic, 15-seater sub. And two in one, a pack with a Military Sub and a Normal Sub.
NOTE: I suggested it to [GSF]Ghost and he said there already is one. What was it? Aviator Submarine. :\
Deathmatch (By Space Guy) (RTB)
Got me an idea of this...
Halo Deathmatch
As an add-on for Deathmatch and a setting like TDM Team Setting with all the status for Halo. Not a long description :\
NOTE: This can also be done with Slayer. Idc how.
I would have more. Just PM me about an idea you wanna know about.
