If you’re in the mood to shoot some undead monsters in the face, then this weekend’s Steam Deal might just the thing for you.

Killing Floor 2 is free to play until Sunday afternoon. This means anyone who meets the minimum requirements and doesn’t mind a 10GB download then you can get in on the co-operative Zed killing action with the wave of new players this free weekend will bring.

If you’re more of a solo FPS players than Bethesda’s discount on the entire DOOM franchise might be of more interest. Almost every entry in the series – except for the upcoming 2016 reboot- has been discounted. Honestly the price difference between DOOM 3 standard and DOOM 3 BFG, which includes the Lost Mission Expansion, is less than $1 USD. If you’re going to go for anything DOOM related, that’d be my pick.

Here’s a full breakdown of all this weekend’s Steam Deals:

Doom 3 Pack (Includes Resurrection of Evil) – $4.75 CDN
Doom 3 BFG Edition – $5.49 CDN
Doom Complete Pack (Classic DOOMs, doesn’t include DOOM 3) – $5.77 CDN

Killing Floor 2 – Full version Free to Play until Sunday at 1PM PST. Can be purchased for $22.10 CDN
