Yes there are 3 campaigns but I have to say, the other 2 were kinda lackluster and knocked the steam out of the game a little bit. These things happen on such a low budget title but there's no denying that there's a lot to be desired here. Maybe they'll get enough sales and once Ebola 4 comes out they have more resources to work the kinks out of it. The game is there though.
I am playing Metro Exodus. It is a story driven action adventure stealth survival horror game (yes all of them) with a sufficient budget that doesn't really bring anything new to the table, but it is a solid experience. The characters are great and the atmosphere is fairly rich. While the game play is not very deep, there's enough crafting and customization options to keep it interesting.
The game has sold 6 million copies since its release and one of the the developers has recently died fighting for Ukrainian independence so my condolences there.
I took a look of some full game walkthroughs of Ebola 1 and 2, and Ebola 3 is quite a step up in everything from graphics, to level design, to variety of level design and gameplay. The series seems to have a cult following that is growing.
Yeah I've played all the Metro games. Regarding Exodus though, it's kind of funny how my first reaction was I didn't like it as much as the first two, but then I went back to it and played it again, and this time it felt much more immersive to me. The only thing I can explain would cause that is being in a bad mood for one reason or another and expecting it to play more like Metro Last Light Redux, but oddly enough, this time I was glad it had it's own design.
I think part of it though was I was more familiar with it this time around, and knew how to prepare better for some of the tougher battles. I also like how there's a decent amount of extended gameplay with the Sam's Story and The Two Colonels DLCs, both of which are pretty good.
