Highlights of this update are the requested single-stage mode and persistent in-game achievements to add some replay value. The normal game mode is now called Campaign mode.

Single-stage mode (a.k.a. practice)

Play any unlocked stage with as much power and resources as you want. Use it to practice a stage under specific conditions, or give yourself full power and take out your frustration on that stage you’ve been struggling with.

This mode does not save scores or medals or advance stage progress.

Achievement medals and bonuses

For each stage and difficulty level, you can try for these four achievements to earn bonus points and persistent medals.

• Don’t die
• Don’t miss a heart
• Don’t lose an ally
• Save all friendlies (where applicable)

Other stuff

• Pause menu tells you where you will restart, and that ending the game loses your checkpoint. Reduced hold time of restart and end buttons to 1 second.
• Halved ally shot damage.
• Fixed cases of zombies coming up from behind without warning before the 6th boss.
• Slight final boss adjustment.
