A lot of potential here. Graphics and concept are strong. The mechanics could use some work: More challenging missions. Medic skill and stimpak could be useful if enemies were more difficult. Fix power stat so it's meaningful (right now, monster hp is so low you don't need to spend points on stat) A more flushed out narrative would also add to the gaming experience. Looking forward to a sequel.
An excellent sequel. A few suggestions:
Bring back the zombie graphics on the main map from the first 'Rebuild'. Not only did it help with the gruesome mood but it gives the player an 'at a glance' view of where the zombies are massing which is great if you're looking to thin their ranks a bit.
The strength of this game is really the writing. Adding more random events and situations to the game would increase it's replayability imho.
