# Alien Swarm arcade game vs Retro Grid

The clearest difference is in-app purchases: Alien Swarm arcade game at none against Retro Grid's 3. Alien Swarm arcade game also leads on review sentiment (44% vs 26%). Retro Grid's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 14 months). On price, rating and device support there is nothing between them.

Both are free to download. Retro Grid sells 3 one-off in-app purchases. Alien Swarm arcade game asks for nothing beyond the download.

Retro Grid holds the better App Store score, 3.5 against 3.3. That said, the two scores are not equally well evidenced: Retro Grid has 34 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 44% of Alien Swarm arcade game's written reviews are positive against 26% of Retro Grid's, so the app with the better star average is not the one people write more warmly about.
