You might remember Deadlight from one of this year’s Summer of Arcade titles on Xbox Live. The zombie platformer will get transferred to PC soon for a Steam release. There’s another developer diary that comes with this announcement.

In this clip, developer Tequila Works discusses just how to create the game. First, they must create little problems for the player to overcome. Then they create a path through the level. Timing here is important, as people who’ve played the game could agree. It even matters where zombies are placed. The main goal is to keep it fun, but often enough a plan will need to be rethought and the creators will have to return to the drawing board.

There’s also an insight in the world of game testing, which is not as amazing as it may sound. A resident tester admits to playing the full game over 50 times and racking up over 500 deaths. To get there, the developers tried putting in different situations. Inside of buildings, only a few zombies would be scattered that could be avoided through one’s wit. However, the outside would be crawling with death and there mobs should be avoided. Other situations might require the use of weaponry. They also discuss altering the user interface and putting in small details. One small detail we personally liked is that one of developer rocks a sweet Mass Effect sweater.

Unlike other characters, Tequila Works would imply that their protagonist is a regular guy. They probably mean the part that’s not filled with parkour elements. They define their game like a puzzle game with zombies. We thought Plants vs Zombies already did that.

The Steam version of Deadlight comes out on October 25, 2012. It’s a dedicated version with enhanced graphics, the inclusion of a soundtrack and even a Nightmare Mode. That last one strikes us as odd, since most of the critique given about the game is that it’s so filled with trial and error that it becomes unfairly hard. The ending is barely reachable without the game spiking the challenge. We’ll need to see how that works.

Speaking of Xbox titles coming to Steam later on, the Skyrim DLC Hearthfire is out now. It’s available in these languages: English, French, German and Spanish. For a mere €4.99 you can play The Sims in the world of The Elder Scrolls.
