Yes im almost certain we can. Ive been looking into that for awhile
The trick is that we need someone to do the NIS sequences and someone to adapt the SCAR code.
O4B is teaching me SCAR atm (fucking hard... I gotta learn how to use functions) but he's gotten working SCAR code to spawn units on the map and to make Arty barrages work at the start of the game like we had on old St. Lambert.
It's not a far stretch to consider NIS videos setting up the premise for an objective based EIRR game, but O4 is just experimenting and Im still learning.
Here's the How-To on getting an NIS video to play before a multiplayer game.
