Yes indeed. I just set your Zombie Nurse stronger in the game as well as other Zombies. Even though I have played many test games now, I still get a kick out of the novel and fun units. There are many new additions in now that have developed the game more. The Farmers will ultimately need to have several units replaced and we still want a Monster Zombie that fits his role in the game as the BIG BAD Zombie daddy to contend with. The current Monster Zombie works but since it is just an enlarged and re-colored Romero Zombie, it would be more fitting to see a more gruesome Monster, graphically. I really like the Alpha Zombies, they fit perfectly and are Great. Oh, the Chainsaw Maniac and Highway Patrol are in and work very well.
odintheking... "no worries mate", if you have the units before the release we can add them. At this point we are waiting on the Old War Vet and Company Car units that are being worked on and because the Crawling Brain is needed by the Zombies, I have to make that after completing the Faction game play and unit settings. The Play testing and Faction Adjustments are about finished so the entries in the Civilopedia can be adjusted for all of them and any written entries completed. Thise are also mostly completed but do need adjustments and some additions.
There have been thousands of things made and adjusted for this game...it has been quite a laborious chore for a very long time but one that will be worth all the efforts. It will be more complete when released than what was first expected. We want to have as many of the Units that will be replaced as we can before the release because people become accustomed to what is in a game...if that is changed, it alters the look and feel of what they have been accustomed to seeing. This can be Good and even better but most people are "creatures of habit" and don't like change, lol.
...there is still time so if you can manage to complete any units, we can add them. The "Flamin' Hero and Pyromaniacs for the Farmers and Survivors will be seen a great deal in the game so if you can only make one unit type, those will have the most use. As I mentioned before, you can make one unit then we can either re-color it or if you want to add any simple changes to make each look different that will be great...the same but different. This will gain the most from your efforts on one unit. The First Hannibal upgrades quickly in the game as well as the second Hannibal. The Flamin' Hero (Pyromaniac) and normal Pyromaniacs are then seen for the duration of the game for the Survivors and Farmers.
Lord Malbeth... do you have a link for those units? Always like to see new units because even if I cannot use them in one game, I can in others.
