Sol Survivor

Sol Survivor Developer: Cadenza Interactive Publisher: Cadenza Interactive Tower Defense - PC HD Backup 1 player, Multiplayer Co-op & Versus

Now that I'm packing a modern PC, I'm experimenting with PC gaming.  First order of business, some indie packs from Steam.

I picked up Sol Survivor as part of a Strategy bundle. Turns out each of the 5 games in the bundle is some sort of tower defense variation. Lucky for me, I generally enjoy them. For those of you who aren't familiar with the genre, tower defense games feature maps, where waves of enemies traverse a fixed (or not-so-fixed) path. If the enemy reaches their destination, you lose life.  Hit 0, and it's game over.  The goal of the game, then, is to build "towers" that attack the enemies and hopefully kill them before they ever reach you.  As you destroy enemies, you earn the ability to build more towers or upgrade existing ones.  The fun of the genre comes from understanding the specific nuances and special powers of your "towers" and placement of those towers to do the most damage.  For instance, most games of the genre will usually have a tower that can slow down the enemy, but does little or no damage.  That's a great supplemental strategy to use in conjunction with offensive towers, but not good by itself.  So the right blend of towers is required.

That description generally applies to all tower defense games.  Sol Survivor is a pretty standard entry to the genre, and as such, makes a good intro.  The setting is very sci-fi, with an alien invasion as a backdrop.  Instead of towers, you have turrets, each with their own strengths and weaknesses.

There are two design decisions that make Sol Survivor distinct.  There's an "Orbital Support" system that makes the game more interactive than its peers.  In addition to the ability to build turrets, you have an energy bar that you can spend to alter the game.  While your turrets are shooting at the enemy, you can click on the Laser Orbital Support, point at the enemy and then hold down the mouse button.  A laser beam will follow wherever your cursor is to do additional damage.  This is especially handy to finish off foes that weren't killed by your turrets.  There are other orbital support options - some enhance the abilities of your turrets by giving bonuses temporarily; some will slow down any enemies within a radius; some will deal direct damage to an enemy like the laser.  The orbital support system helps to make the game more action-focused and less passive.

While the Orbital Support is a significant addition, the choice of Officers has an even greater impact on the gameplay.  This is the first tower defense game I've played where you don't have access to all the towers in the game.  Sol Survivor makes you choose from 10 different officers, each with their own subset of turrets and orbital supports.  What this means is that each officer has a different playstyle and strategy to employ.  This was my favorite aspect of the game.  There are a total of 20 stages in the campaign, but I found myself replaying the same stages with different characters just to get a feel of how the game changes.  By limiting the types of turrets you can build and mixing up your orbital support abilities, the developers made the game better as a result of those restrictions.  You're forced to make do with what you've got and it gives the game more of a personality.

In addition to the single player campaign, there is also a single player survival mode where unlimited waves of enemies come knocking at your door as well as a co-operative multiplayer experience.  I haven't had the opportunity to try the mp game, but according to the videos I've seen, it looks like it works really well.  If you're a completionist, there's tons of achievements both in the game and through Steam, that will keep you occupied for many many hours.

Still a generic tower defense game overall, but solid.  The addition of orbital support and multiple characters doesn't drastically change the genre, but they sure make things more interesting.
