Mars: War Logs, clearly borrows from better games and although it won't set the world on fire, it is solid enough to get a few hours of entertainment from.
You start the game in a POW camp and are swifty introduced to the main character Roy as he rescues a new immate from the less than romantic attentions of a fellow prisoner. After this "edgy" but oh so cheesy opening, you are tasked with attempting to escape from the prison whilst completing numerous side quests.
As to the side quests, they don't offer much and most of them revolve around collecting X amount of Y or hitting people until they stop moving.
I won't go to much into the story, not because I will spoil it, but because it isn't something that hasn't been done a million times before. It is not that it is bad as such, it is just very generic and uninspired.
Although, the game has RPG elements, they are fairly basic and amount to upgrading a couple of dozen skills and some item crafting but most of the skills have little impact on game play and you can get through most of the game without needing to craft anything,
The combat, like much of the game has been done before and if you have played any action game in the last 10 years you should pick it up instantly. You can perform a couple of types of attack, block, use hot key special moves and roll, oh how you can roll.
They do attempt to spice up the fighting by giving you the option to issue commands to NPCs who are with you, but I never used it. But, it is there I suppose.
Overall, Mars: War Logs is an average game but it makes a good distraction and there is the skeleton of a good game buried within it, and for a budget title, you could do a lot worse.
