Robotron 2084- with upgrades!
This game has beautiful graphics- all of the robots look wonderful right before they blow up ;) And the gameplay difficulty is set just right to get a little harder every level, which forced me to stay on my toes! I really liked thet fact that upgrades carried over to the next level, which helped clear out enemies and kept the multiplier going. This is an excellent tribute to Robotron! Superb job!
