Victor Salalaiko (also known as BelaRUSSIAN) is the creator of two custom map sets for Blood.
Defrag contains five maps, with each its own episode.
- "DeFrag" - "huge space for jumps with napalm, blow barrels TNT and fly where you want, additional rooms for other tests and it is a lot of that another. More shortly, it is possible to make everything"), "Blooders" - originally reflected as a map for network game, but still in DeFrag, because requires completion."
- "nJUMPing" - "jumps with napalm through a trench. Simply for those who wants to try."
- tJUMPing - "jumps from dynamite. More similar on run with obstacles: look demo."
- "FireBall" - "similar I saw in Quake: fly on you rocket, but in Blood napalm. Fascinatingly."
Bots contains three maps intended for hard core players, with each its own episode. The author's favourite is "Cultists".
