Two types of invasion (The alpha and the delta spit in two episodes) with 10 maps each... really awesome! You can spend hours playing this... really cool to play with different type of wads, especially weapons. Not made by me. It was made by Zalewa, credits go to him and anybody who helped... Enjoy!
Awesome!! You can spend HOURS playing each map... Way more fun if played with a lot more friends... Download now if you didn't yet... With other mods it can be even more fun... For instance, i play with insanity mod (more than 20 new weapons, different monsters and stuff) it gets way harder and cooler, because there are more weapons to kill the endless horde of minions from hell!! Hahaha 10/10
