1/5 because of lack of descriptions and balance issues... How do I get fuel when I run out, for example? What's the difference between resolve and sell? Just a little bit of time is helpful.
Not bad...The only problem is that if you go the "angelic" route (& don't buy anything except the flame thrower & pump shotgun), then you become unkillable...With the full upgrade, you take damage to almost 0, but then pop back up, take damage, pop back up... Even after fully upgrading the other skills (& the rage penalties), all you have to do is stand in one spot and the game goes on forever. I finally got bored with about 2500 kills and just moved, which took out the regenerate & protection, & I died.
Some sort of end would be nice other than just giving up :)
Nonetheless, 4/5
Still waaaay too laggy. I get bogged down after emptying my first clip into the final boss, then it's just run straight into a wall and fire at nothing until I'm dead, since I can't control anything.
Re: unable to place "towers":
If you quit the game, leave the page, and come back, when you try to place a tower, if you click on the place, the gunner goes "grey" and no tower is placed.
