Spider-Man: Edge of Time

To get all the Golden Spiders, check Keosky's guide under that achievement.

If you've gotten all the Golden Spiders throughout the game, this quarter mark achievement will pop in Chapter 5. When you first meet the Mother monster, there is a challenge to beat 15 enemies in one minute. Mix up quick attacks, strong attacks, long range attacks and of course your time freeze attack to pound these enemies. Try to focus on the soldiers to start, as it will give the monsters a chance to spawn, filling the room with more than 15 enemies and increasing your odds of success.

Once you score gold in that combat challenge, you will be rewarded with the chapter's 4th and final golden spider, which also happens to be the 25% complete mark!

Note: The best way to gauge completion of golden spiders is through the Chapter Select screen. It will show you which ones, if any, you might have missed.
