So I finally got a chance to finish up a playthrough with the new DLC. Some good stuff in it and it definitely changes up the gameplay, (mostly on the worldwide strategy level) but just like the vanilla game, the late game becomes a victory lap once you have a maxed out squad and a few certain skills/items. (especially once you've defeated the chosen and the alien rulers)The DLC provides even more help in that regard.....
- Squad member bonds give you the ability to grant extra actions at key moments.
-When you finally kill the Chosen, you get their weapons, which are insanely overpowered
- The new perk system allows you to load up your best soldiers with tons of extra perks (you can give your snipers all the pistol skills AND rifle skills and make your specialist a medic AND hacker) This is extremely unbalanced.
-The 3 resistance factions heroes you get are VERY good once you get them maxed out.
-The game comes with some new items that I didn't even really try out, but I imagine they would have helped as well.
The Chosen show up on a lot of random missions (and pick up new skills as the game goes on) but they usually hang back, so you can clear most of the map before you fight them (so you dont get caught fighting them AND a pod all that often). But they are fun to fight.
Other stuff they added that was pretty good....
-a handful of new enemies that are mostly pretty tough. Nothing crazy though.
-several new mission types
-the 3 resistance factions comes with special bonuses and you get to do covert ops (you just send guys out on missions and they come back a few days later. You dont actually do the missions unless you are "ambushed" (which is random) for additional rewards. The downside to this is you can do missions that stall the Avatar Project (I basically had it at like 2 bars for the whole game)
-They added soldiers getting "tired" or "shaken" which makes you develop a deeper group of soldiers. Certain soldiers develop negative traits (forced reloads, more likely to panic against certain enemy types, etc) if bad things happen to them on missions.
Plus I'm sure there's plenty of other I missed. In terms of additional content, its definitely worth the $$. They also add some additional cinematics at the end of the game which hint at the next game.
Overall, it was fun and definitely made the game feel fresh. But just like before, you basically need a lot of luck early (good RNG and avoiding activating pods you aren't ready for) and then the late game is too easy. On the last mission (Commander difficulty, Ironman), not only did I not lose any soldiers or even take any damage, I didn't even have the enemy take a single shot at me. (even without using a single grenade, a lot of my more powerful skills or the heavy weapons on my 2 WAR suits) I may have to try IMPOSSIBLE the next time I fire things up.
