Steam's annual Summer Sale has begun, and with it dozens of games have received heavy price cuts. As always, some games are selected for flash sales to have even lower prices for a few hours. Additionally, like last summer, there's a community event that can lead to other discounts, although nothing has been unlocked yet.

　　Notable games on flash sales include:

　　Black Mesa (Remake of Half-Life): $16.99 (Down from $19.99)Fez: $1.99 (Down from $9.99)Papers, Please: $4.99 (Down from $9.99)Mirror's Edge: $9.99 (Down from $19.99)Check out these other games on sale:

　　Don't Starve: $3.74 (Down from $14.99)Homeworld Remastered Collection: $13.99 (Down from $34.99)Metro 2033 Redux: $6.24 (Down from $24.99)The community event works by using the summer sale badges that you can acquire by buying games on sale. You can also receive them by crafting game badges or trading with friends. Then, using those badges, you can join the "Monster Game" to "fight enemy monsters as you heelp your team level up, unlock new abilities, and achieve community milestones," as the Steam page explains. If your team does well, you can unlock discounts on games for the entire community.

　　The next set of flash sales begin in 12 hours.

　　Personally, I'll probably buy Metro Redux and the Homeworld Collection. What are you going to buy, or what games are you holding out for? Let us know in the comments.
