I like this game really much ;D
it developes strategy skills and it teaches you decisions such as what can you risk.
it is easier to keep a small group so your people wont starve.
I like the second choice with the swat and gangster.it is good and requires less supplies to keep the group alive....the biggest group i had was 6 and 2 died of starvation and the others had low health so they died on missions..,TIP:it is better to keep a group from 2-5 men(If you have saved some supplies)
You did a good job with this game and it doesnt feel like demo...
I think that you should add more Guns and Characters E.G juggernaut(HIGH HEALTH) Soldier(medium health and attack) Doctor(revives faster and has low health) and stuff like that
OH! and a customizable base with things like diffrent watch towers,walls,fences,house
As i said before NICE game and keep up the good work guys!you have my support
