The Long War Alien Pack fits neatly into Better Advent's lineup. So good, in fact, that i recommend using both as a new default way of playing with ABA. My "All The Enemies!" plugin makes these mods play together without any problems.

In addition to the usual compatibility stuff that i do with All The Enemies!, i also did some other things to rebalance certain aspects of the LW Alien Pack to fit right into my lineup. Some of these changes are made directly in ABA, others in ATE!. Assuming, you use all three mods as recommended, the following changes are done:

Troopers:

- ABA Sentinel Troopers no longer spawn. The LW Sentry Trooper does the same job, but much better.
- ABA Demolitionists tiers 2 and 3 no longer spawn. The LW Grenadiers replace those.
- LW Grenadiers Tier 1 no longer spawn (instead being replaced by the ABA Demolitionist). Tier 2 and 3 spawn earlier each.
- LW Grenadier Tier 2 loses his fire grenade for a frag grenade, Tier 3 loses his acid bomb for an alien grenade. There's already plenty of area elemental bombing in ABA, i feel like adding even more is too much of the same.
- The LW Gunner, Rocketeer and Sentry got slight adjustments to their minimum forcelevels, usually by +1 or +2, making them appear just a little bit later. I also removed most of the overlapping forcelevels where both the tier 2 and the tier 3 version could spawn in the same pod.

Chryssalids:

- LW Chryssalid Soldiers can appear as leaders to ABA Chryssalids or as followers to Chryssalid Royalty (King, Queen, Hive Queen)
- Removed vanilla Chryssalids from the followerlists of LW Chryssalid variants and replaced them with ABA Chryssalid tiers.

Vipers:

- The tier 2 and 3 version of the vanilla Viper is only available as a pod leader for 2 forcelevels, after that it gets demoted to follower status to make place for the more interesting variants like ABA Boas and LW Najas.

Archons:

- The tier 2 version of the Archon is only available as a pod leader for 2 forcelevels, after that it gets demoted to follower status to make place for the more interesting variants from ABA.

Sectoids:

- The LW Sectoid Commander spawns as a pod leader for a few forcelevels at first, then becomes a follower in the endgame.
