Finished it. The campaign is around 25 hours long, fun to do it once but don’t expect much. The usual xcom turn based game with unusually more bugs than in the base game which is wierd because it uses the same engine, assets, maps etc. New gameplay elements are the breaches before each encounter and the introduction of turn order. Not my favourite parts, breaching is fun for the first couple of hours then it is just a neccessity. XCOM dared to explore new options which i respect and it done a good job with it but i would not carry any of it over to xcom3. Very well priced for the content, not too long, not too short, worth to play it through once.
