Total-conversion mod for SWBF2 that adds the Mass Effect era to Instant Action. You can fight as the Systems Alliance, the Heretic Geth, the Collectors, or the Evolved Geth on six new custom maps, all of the stock maps, and all maps from the Sol Map Pack.
Not sure if it'll make the next version or not, but there's at least one more on the way. This map has been killed and restarted twice now. But it's definitely been worth it, we love this part of the ME3 campaign.
"This is Rannoch, the world of our ancestors. Our bodies carried the seeds that spread the desert grass." - Tali'Zorah vas Normandy
To-do: Add custom Rannoch foliage, crashed and burning ships, fix collision and low-polyness, add nighttime environment to alternate with the dawn one, and some kind of Geth base. And maybe Quarians.
