I just packed some Biolab Disaster's entities together. The pack mostly contains "logic" entities that are not directly visible in the game. These entities are ready to be used in your project.
Visit your download page for the link.
The Entity Pack includes:
EntityTrigger– a generic trigger entity, that does something when touched
EntityDelay– a delay that can be used in conjunction with a trigger
EntityHurt– gives damage to the activating entity
EntityLevelchange– loads the specified level when triggered
EntityEarthquake– shakes the screen when triggered
EntityMover– an example of a simple moving platform that visits all its targets
EntityParticle– generic particle entity
EntityDebris– spawns a number of particles when triggered
EntityVoid– does nothing; can be used as a target for movers
