STG's

The Rhesus Chart - by Charles Stross - was another excellent entry in the Laundry series. I read this on release, but this was months ago, so I'm just going to say that I really enjoyed it, and I really want to see what the follow up for this will be!

Broforce is an interesting retro 2D platform shooter. You play as several 80s movies characters, such as Rambo, Ripley from Alien, Robocop, TimeCop, MacGyiver (one of the best - throws explosives), etc, etc. Each has their own different guns and skills. And every time you die or free another one (they are in cages around the levels) you switch. It is still an Early Access game, and since it is been this way for so long, I'm not sure if there will ever an official release, but it is playable now. The coolest part is how explosions and fires can destroy pretty much everything. There are plenty of user maps available, too. The most annoying thing I can think of about it is that your firing range can vary a lot from characters to character, and can be a lot less than your enemies. Overall, pretty much recommend for the price.

Space Run is an interesting variation on Tower Defense (TD) - you design a ship that has to quickly cruise through a set of pirates and asteroids to make a delivery. You get a few variations on guns, engines and shields, that are upgraded as the levels go, and you also get to re-do levels to get more money (although unlocks require using the max stars on each level instead). Difficulty increases sharply on replays. Graphics are reasonably good, and playability is good on the first few levels, but gets a little annoying later. Unlike most TD games, you often have to rotate your guns or activated some special items, but you don't have any way to pause. Overall, pretty good, but ultimately can be a little frustrating.

Plague Inc: Evolved is an interesting sim game where you try to make as much damage to the world as possible as choosing the best place to start and the right genes to make a dangerous disease. It is still on Early Access (i.e.: beta), but it is still pretty fun. I last played several months ago so it has several new features, but I found it already somewhat interesting for the price.

Desktop Dungeons is an interesting roguelike with retro graphics in which levels almost feel like a puzzle. Mostly you go around fighting enemies (that do not move at all). You get a nice prediction of what will happen on your next attack, and can go around walking through undiscovered tiles to regain health. You will slowly improve your level so that you can kill the harder enemies in the maze. It can be pretty though since the difficulty is calculated so that you will use the spells and special actions on a nearly exact manner. It ends up being a bit too tough for me, otherwise I would consider it to be quite fun.

IonBall 2 is an interesting Arkanoid clone, with a spaceship theme and plenty of guns and upgrades. It has some interesting semi-original ideas, and wildly hectic gameplay. The one major issue I (and a lot of people, just see other reviews) have with it is that the effects can make it very hard to keep track of the ball. Other than that, very enjoyable.

Drunken Robot is a bullet hell FPS with procedurally generated graphics. It is almost good, but personally I didn't enjoy it at all.
