You can now view these two games on the mobile game subscription service.

Galaga Wars and Kingdom Rush Frontiers TD joined Apple Arcade on Friday. Apple's $5 monthly mobile game subscription service allows you to play more than 220 games on multiple iOS devices.

Galaga Wars is based on the original fixed shooting game in 1981. Dive into the nostalgic instant shock wave and destroy the endless shock of aliens and other enemies. Each ship has different abilities, so you can change your strategy. 

Galaga Wars is already available in Apple's App Store, but with this standard version, you will encounter in-app purchases and advertisements. By subscribing to Apple Arcade, you can unlock the game completely without ads.

Kingdom Rush Frontiers TD on Apple Arcade. 

Kingdom Rush Frontiers TD is an exciting tower defense game, a follow-up to the Kingdom Rush legend (also available on Apple Arcade). Defend the kingdom from dragons, greedy plants, and the inhabitants of the underground world. Build and upgrade more than 18 towers with different abilities to best suit your defense strategy. Choose from 16 heroes to train and fight against more than 40 enemies.

In addition to the new games, you can also check Spire Blast, Temple Run: Puzzle Adventure, Sping, and Lego Brawls for updates. You can look forward to Dandara: Trials of Fear, Splitter Critters and more upcoming services.
