Undertow is an underwater shooter set in an alternate world, featuring a 15 level campaign for single-player or co-op and two multiplayer modes for up to 16 players. A certain amount of maps have level-specific goals and the core gameplay of the game is centered on the idea of destroying as many enemies as possible, while also staying alive for as much as possible.

First of all, gamers select their race and unit type, after which they're ready to fight. Each of the three races features four unique, upgradeable unit types ranging in ability from the fast and agile to the large and powerful. Players can unlock and purchase unit upgrades as they acquire points. Each unit type has three levels of permanent upgrades and yes, it seems that three is the magic number here. And, just like in every other game where you have loads of weapons and abilities, points and power-ups can be used to further upgrade unit abilities.

We know that true gamers play all these games just for fun, as they should, and not in order to achieve specific point landmarks to prove to their friends they are very cool, but we also know that sometimes you just can't live without achieving everything possible with a title you really enjoy. If that's the case and you want to know exactly what to look for when it comes to this game, we have prepared a full list of achievements for you. Good luck!
