Hey im having trouble with one of the maps in this its not the mod its the map design its self i think were when the rebels harvest scrap they some times get stuck behind it in meltdown when they would walk over the scrap and just get stuck behind the level and theirs a hole were some of my soldiers got sucked down and could not get back up D: .

I'm talking about the bottom left scrap pile they would get stuck and never be free and that holes around that my men got stuck in and the cover system is terrible theirs cover but you can't take cover.

PS- STRIDERS ARE OVER POWERED IF YOUR ONLY REBELS unless you have an army of rockets but are easly killed by combines and hunters PLEASE FIX THIS

Its only €6.99 on steam right now, you would be shooting yourself in the foot if u did not buy it,

There are hundreds of very goood good mods out there that need this expansion.

Dont think your only buying epsiode 2, think your buying Acces to a large amount of Comminity Mods, that will prolong your playtime by at least 500 hours, if all played !!!

When im playing against CPU, my rebels wont destroy all buildings. only HQ and housing. And I don't get a Win message when my enemy is gone. the game goes on forever on Annilhation. Possibly add the ability to move/remove buildings that you built or add the ability for Units to go around buildings so they dont get stuck? Thanks. And can you possibly bring back the Scenarios from the older version of the game? They were very fun to play and now i can only play against bots...
