A new week has dawned, and with it comes a new list of great things happening on Android. This is the Google Play App Roundup where we tell you what needs to be on your phone or tablet right now. Just click the links to head to Google Play and grab these apps for yourself.

XDA is a well-known source of modding and customization chatter, but it can be tedious to dig around in all the specialized forums and articles to find useful things. The new XDA Feed app is a curated list of mods and tips for your phone or tablet, and it's free with no ads.

Some sites have their own apps that merely replicate the site in a different wrapper. I've never been fond of these when the mobile sites are usually more convenient to use. XDA Feed carves out a niche by limiting what it shows you to the best or most interesting stuff, chosen by the operators. The main page has a list of selected items across a number of categories like ROMs, icon packs, wallpapers, and more.

XDA Feed is an excellent example of material design. It defaults to a dark UI mode, but there's a light one available in settings. You can move between the main feed, starred items, and a filter list. Filters are handy if you're interested in things like icon packs, apps, and wallpapers, but aren't into flashing ROMs or custom kernels. Although, those last two are big deals on XDA.

Tapping on an item in the feed brings up all the relevant info from XDA, whether that's an article or a forum post. Everything loads in the app with buttons that can open the source in your browser or download the content. In the case of apps and icon packs from the Play Store, the download button links you to the listing. For wallpapers and other items, it's a direct download.

The default setting in XDA Feed is to get notifications of new items. So far this isn't too annoying as only a few pieces of curated content are added daily. However, you might want to play around with the settings so you're only notified with certain items are added.

This app is still in the early stages of development, but it seems solid. I'll be interested to see where it goes.

Naval strategy is a difficult genre to get right on any platform, especially mobile. It usually requires too many controls and is slower to lay than other warfare games. I've played a few on Android that were fun, but they tend to be rather involved and not very friendly to bite-sized gameplay. Enemy Waters seems to strike a good balance between accuracy and simplicity.

In this game, you command the fleet of the king, who if I'm being honest is kind of a jerk. He only rules three islands in this unnamed archipelago, but with your help he'll be able to take more territory from Pirate Little John, who is a bigger jerk. At your disposal are 10 submarines and 10 warships, many with their own special abilities.

In the main campaign mode, your goal is to dominate the entire map. Icons appear to represent missions, some of which represent new structures and resources to capture. Certain locations will generate oil or cash, which help you take on more missions and upgrade your fleet. Most missions include a mix of ships and subs, and you can plan the attack on a map. So, the vessels you are not controlling directly will follow your orders during the battle.

Controls for ships are very straightforward. You've got a throttle on the right and left/right turn buttons on the left. Double-tapping fires the main guns, which are aimed by tapping and dragging. You'll do more damage if you're firing broadside at your target as both deck guns fire. There's also a button for dropping depth charges, essential for taking out enemy submarines.

As for your submarines, the controls are similar. You have a throttle, left/right buttons, and you can aim your torpedoes. The submarines also include controls to dive and surface, and a silent running option. It's up to you if you want to stealthily sneak up on the enemy and pick them off, or cruise in with all guns blazing.

The graphics are impressive and highly configurable. You should be able to get the game running well even on modest devices, and high-end ones can make Enemy Waters look very nice. The ships are quite detailed, and the animations are smooth. There's even adjustable anti-aliasing, so the edges are nice and smooth of your device can hack it. Frame rates are solid on the Pixel with almost everything maxed, but the device does get toasty.

Enemy Waters is free, but there are some in-app purchases and ads. That said, the game doesn't really push them. In fact, you can't even buy anything for about the first hour or so of gameplay. It's like a loosely guided tutorial.

When I saw the title "Turretz" I was expecting a formulaic tower defense of some sort, but some cool things have come from this developer in the past. I gave it a look, and I have to say Turretz is a nifty little game. It won't blow you away with graphics or storytelling, but it's a fun arcade-style space combat game.

In Turretz, you are in control of a small planet besieged by wave after wave of enemy projectiles. Your planet is not completely defenseless, though. You can build and arrange giant defense towers on the planet that will eliminate some of the projectiles. You're still going to get blown up, but it'll take longer. How long depends how effectively you spend your resources on upgrades. The planet rotates, and your weapons fire. When you run out of hitpoints, it's game over.

Each run is slightly different, so the outcome varies based not only on your maneuvering but on random chance. The waves have approximately the same strength, but it's a little different every time. You arrange your weapons as you like, but they fire automatically. Your only interaction is moving the planet around the screen, which is done with a tap and drag. It has 1-to-1 movement no matter where you press, so you don't have to cover up the planet with your finger.

There are a lot of neat weapons to choose from, like the multi-missile launcher, freeze ray, and a giant drill. However, there are only eight mounting hardpoints on your planet.

Turretz has a definite retro 8-bit look, which is common for games developed by 111%. It's done well, and I don't think the simple graphics are a result of laziness. Even the larger boss enemies that could be more detailed are giant pixel-art creations.

Turretz is free to play, if you don't mind at ad on the screen. It's actually in a rather annoying place at the bottom of your screen, covering your wave progress. It's only $0.99 to get rid of it, though.
