Since Exodus From the Earth is on sale once again, I guess it would only help people's decision out if I posted this. The moment that you start playing, the first thing you'll notice is how bland the graphics are and how bad the voice acting is. To it's credit, however, it came out almost six years ago, but the voice acting goes unexcused. So it's only right to give it the benefit of the doubt and ignore first impressions. Unfortunately, that's the least of the game's problems.
What I noticed throughout is how odd the audio is. For some reason, there's this small static that occurs and it's more noticeable when you're wearing headsets. After a while, I got over it, but then comes another problem. Pressing the "Esc" key to go to the menu will play another song. Unfortunately, this song will interrupt the game's current music and continue to play after exiting back. Which is a shame, cause it can ruin the environment of your current mission when you want a break. Not to mention it can get tiring to listen to a bland voice making a "dramatic" speech. As well as having that speech play over soldiers shooting at you.
The gameplay is generic. It's the typical First-Person Shooter genre you would expect, but I have some issues. In many instances, the enemies have abnormally accurate weapons. I understand that this story takes place in the future, but even on easy mode, I still have to be careful, or I lose a chunk of my health quickly. Exodus also enjoys recycling levels. You'll eventually ask yourself "Wasn't I here before?" And even realize that they recycled a crate depot three times (And you will notice it, as it is just a complex maze.) To add on to that, the four last levels on the preview screenshots do not exist in this game so there goes the defense of variety. At least there's vehicle driving, but poor controls somewhat cripple it and only two locations of the game have this. Be warned that you can stuck in several areas, as well. That includes the vehicles and the straight-forward shooting.
The game also has stealth sections. I wouldn't mind and probably have enjoyed it, but because of how poorly programmed it is, scientists will spot you, even when they're a floor above you. You can't stop them, either. Once they try to sound the alarm, killing that man would only grab the guards' attention, anyway. You can always restart through save files to see if you can get through a level without getting caught, but I've tried so many times, that I stopped caring and progressed through brute force. Alerting the guards will welcome you with poor A.I. that won't go through doors to attack you and will even refuse to move at all, so you at least have that advantage.
The story is difficult to follow. And I say this, because the voice acting is so bad and the game is written like a poorly translated script. From what I understand, that is the case as it was made in Russia, but that's still no excuse. Of course, there are even PDAs found throughout the game. Some are translated fine, some have awful typos, and then there are ones that appear to be typed as a joke. Almost like "0mg u guiz g2g 2 dis party in teh office!11!" Very amusing, but the script is still a damn mess. And what do you come to realize the story was all about, once you understand it? A generic plot, really.
To Exodus from the Earth's credit, there's some unique puzzles and challenges that aren't too punishing, such as the last level, that can be fun, but they're not too frequent, either. If you want to try it out of curiosity of a obscure game, go right ahead. But overall, this game had way too many poor design choices and terrible programming mistakes. It's lengthy and difficult, I'll give it that. But it will only make you wish you were playing a better First-Person Shooter.
