Hi! I want to talk about the new details of the developing and show new screenshots.
Supply canister. This is modified headcrab canister, used by rebels for sending ammo and weapons. (without the headcrab, of course). In the beginning of the walkthrough player is allowed to choose what type of ammunition will be sent in this way.

Also I'm working on changing the model of the rebels. Not yet finished, but I hope that you will enjoy.
