I don't really know how to write Lua scripts, so I just copied those codes from here.BulldozerRush And only do a little modify.
*Seems some one has made this mod before but I can't find it.
This mod will replace all assault units with Sniper (SWAT sniper or FBI sniper).ZEAL heavy snipers will only show up in Death Sentence(6 Skulls).
Attention: Sniper assault team has NOLAZER.
HOW TO USE:
Extract and place the folder at (whatever)\PAYDAY 2\mods. You need SuperBLT to make this work.
Note: I didn't and can't fix any bug of the original mod. So this mod may not work at some maps, such as MurkyWater contracts. And it may crash the game in some situations and conflict with other mods. This mod seems has more chance to crash the game. Be prepared.
2020.10.01 Update: Now this mod will work at Murky contracts.
