Re-Blood is a expanded version of original Blood - and it really is! After much thought and the project developing for a long time, the author MaxiClouds decided to release it with a huge amount of features already:

• Reworked weapons! Most weapons have reload, improved sound and effects.
• Now you can carry 2 weapons anytime(full time akimbo).
• More BLOOD, More Gibs!
• Working Delirium mode.
• Beast mode!
• Few reworked maps
• Improved swimming system
• All weapons and enemies from original Blood included.
• Armor system like original.
• Headshot system.
