Im wrong person to say this since Im a huge Alien & Predator fanboy but yes, it is worth it. Multiplayer is a lot of fun and single player is alright.
What are bad points of it are:
- Single player is both easy and very short, provided me with roughly 5 hours of gameplay in total on Normal difficulty.
- Community hasnt established properly yet, hence it lacks dedicated servers totally. Hoping there will be at least some in the future...
- Survival mode is alright but ends up being very dull soon.
- Not enough maps for multiplayer, yet theres plenty of interesting gamemodes which compensates that to some extend.
